Abstract: An inductor component includes an element body, a plurality of inductor wires, a plurality of columnar wires, and outer electrodes. The element body has a first principal surface. An axis parallel to the first principal surface is a first axis. Each inductor wire has a wire body, a first end pad connected to a first end of the wire body and having a large wire width relative to the wire body, and a second end pad connected to a second end of the wire body and having a large wire width relative to the wire body. Geometric centers of the first end pads of the inductor wires are on a single line that is parallel to the first axis. At least one of geometric centers of the second end pads of the inductor wires is not on a single line that is parallel to the first axis.

Abstract: An inductor component includes an element body that includes magnetic powder and has first and second principal surfaces, and a side surface connecting the principal surfaces; an inductor wire in the element body; a first vertical wire that is in the element body, is connected to a first end of the inductor wire, and extends to the first principal surface; a second vertical wire that is in the element body, is connected to a second end of the inductor wire, and extends to the first principal surface; a first external terminal that is connected to the first vertical wire and is exposed on the first principal surface; and a second external terminal that is connected to the second vertical wire and is exposed on the first principal surface. The magnetic powder contains an Fe element as a main component, and the side surface has oxidized and non-oxidized regions.

Abstract: An inductor component includes an element body; and a coil on the element body and wound into a spiral shape along an axis. The element body includes a substrate having first and second principal surfaces facing each other. The coil includes at least one first coil wiring on the first principal surface, at least one second coil wiring on the second principal surface, at least one first through wiring penetrating the substrate from the first principal surface to the second principal surface, and at least one second through wiring penetrating the substrate from the first principal surface to the second principal surface, and on a side opposite to the first through wiring with respect to the axis. The first coil wiring, the first through wiring, the second coil wiring, and the second through wiring are connected in sequence to constitute at least a part of the spiral shape.
