    Abstract: An inductor component comprises an element body; first and second inductors in the body; first and second columnar wirings in the body with end surfaces exposed from a first principal surface of the body and electrically connected to the first inductor; third and fourth columnar wirings in the body with end surfaces exposed from the first principal surface and electrically connected to the second inductor; first through fourth external terminals contacting the end surfaces of the first through fourth columnar wirings, respectively; and an insulating film on the first principal surface covering a portion of the end surface of the first and third columnar wiring not contacting the first and third terminals, respectively. The first terminal is closer to the third terminal than the fourth terminal, and a shortest distance between the first and third terminals is longer than a shortest distance between the first and third columnar wirings.

    Abstract: An inductor component includes a main body formed in a flat-plate shape and including a magnetic layer; an inductor wiring line disposed on a plane inside the main body; a first vertical wiring line that extends, from a pad portion which is an end portion of the inductor wiring line, in a first direction to pass through the inside of the main body, and is exposed on a first principal surface side of the main body; a second vertical wiring line that extends, from the pad portion of the inductor wiring line, in a second direction to pass through the inside of the main body, and is exposed on a second principal surface side of the main body; and an insulation layer of a non-magnetic body. The first vertical wiring line includes a via conductor and a columnar wiring line. The second vertical wiring line includes a columnar wiring line.

    Abstract: An inductor component comprising a spiral wiring wound on a plane; a first magnetic layer and a second magnetic layer located at positions sandwiching the spiral wiring from both sides in a normal direction relative to the plane on which the spiral wiring is wound; a vertical wiring extending from the spiral wiring in the normal direction to pass through the first magnetic layer; and an external terminal disposed on a surface of the first magnetic layer to connect an end surface of the vertical wiring. The first magnetic layer has magnetic permeability lower than that of the second magnetic layer.

    Abstract: A thin inductor component includes an element body having a principal surface and a side surface perpendicular to the principal surface. An inductor wire extends in parallel with the principal surface. From the inductor wire, a first vertical wire extends in a direction toward the principal surface, and a first support wire extends in parallel with the principal surface. The first vertical wire and the first support wire are connected to a first pad of the inductor wire. When a virtual tangent is drawn at a connection point of the inductor wire main body to the first pad with respect to the center axis of the wire main body when viewed from the thickness direction, the first support wire extends from the first pad in parallel with the virtual tangent and the center axis of the first support wire and the virtual tangent are located on different straight lines.
