Abstract: An inductor component includes an element body, an inductor wiring, and columnar wirings. The inductor wiring extends parallel to a planar main surface in the element body. The columnar wirings extend in a direction intersecting with the main surface. The inductor wiring includes a pair of pad portions at both end portions of the inductor wiring, and to which the columnar wiring is connected, and a wiring main body which connects the pair of pad portions to each other. The wiring main body includes a maximum point where a cross-sectional area of a cross section orthogonal to a center line of the wiring main body is the maximum and a minimum point where the cross-sectional area of the cross section orthogonal to the center line is the minimum. The cross-sectional area at the maximum point is two or more times greater than the cross-sectional area at the minimum point.

Abstract: An electronic component comprises a magnetic substrate, a multilayer body including a plurality of insulator layers, and a plurality of coils extending inside the multilayer body. When a first magnetic substrate is viewed toward a third positive direction, an outer edge of the first magnetic substrate includes a linear side. Also, a cutout is recessed inward from the side. When a direction along the side is taken as a first direction and a direction perpendicular to the first direction is taken as a second direction when the first magnetic substrate is viewed toward the third positive direction, a maximum dimension of the cutout in the first direction is different from a maximum dimension of the cutout in the second direction.

The inductor wiring extends parallel to the main surface in the element body. The plurality of columnar wirings extend in a direction intersecting with the main surface. The inductor wiring includes a pair of pad portions which are positioned at both end portions of the inductor wiring, and to which the columnar wiring is connected, and a wiring main body which connects the pair of pad portions to each other. When viewed through in a direction orthogonal to the main surface, one or more selected from the plurality of columnar wirings are connected to the inductor wiring at a location that does not overlap a center line of the inductor wiring.

Abstract: An inductor component includes an element body. The element body includes an inductor wire extending parallel to a first principal surface of the element body, columnar wires extending in a direction intersecting the first principal surface, and outer electrodes. Each inductor wire has a wire body, a first end pad connected to a first end of the wire body, and a second end pad connected to a second end of the wire body. The first and second end pads each have a large wire width relative to the wire body. The inductor wires include first and second inductor wires. When viewed transparently in a direction orthogonal to the first principal surface, at least one of a size and shape of the second end pad of the first inductor wire differs from at least one of a size and shape of the second end pad of the second inductor wire.

Abstract: A first substrate has recesses respectively provided at corner portions of a bottom surface. Outer electrodes each have an electrode body portion provided around an associated one of the recesses on the bottom surface. The electrode body portions each are made up of a plurality of laminated metal layers. A first metal layer located at an innermost side of the plurality of metal layers is formed on the bottom surface at a position spaced apart from a short-side ridge portion between the bottom surface and a side surface.

Abstract: An inductor component includes a rectangular parallelepiped element body containing a magnetic material and having a planar main surface, an inductor wiring, and a plurality of columnar wirings. The main surface has a straight side. The inductor wiring includes a pair of pad portions and a wiring main body. The wiring main body has a parallel part extending parallel to the straight side and adjacent to the side without interposing other parts of the inductor wiring therebetween. A dimension in a direction orthogonal to a center line of the wiring main body and parallel to the main surface in the wiring main body is a width dimension, and a shortest distance from the side to the parallel part when viewed through in a direction orthogonal to the main surface is defined as a specific distance. The specific distance is less than the width dimension of the parallel part.

Abstract: An inductor component includes an element body, a coil on the body and spirally wound along an axis, first and second external electrodes electrically connected to the coil, and first and second through wirings which penetrate a substrate of the element body between main surfaces. The first coil wirings and through wirings, and the second coil wirings and through wirings, are connected as follows. With respect to two of the first through wirings adjacent to each other in a direction of the axis, on the first main surface, a relationship between a radius of an equivalent circle diameter of an end surface of each of the first through wirings and a minimum distance between end surfaces of the two first through wirings is satisfied, and with respect to two of the second through wirings adjacent to each other in the direction of the axis, a similar relationship is satisfied.
