Abstract: An inductor component and a method for manufacturing an inductor component that enables the inductor component to be miniaturized. An inductor component includes an annular core; and a coil including a plurality of pin members and wound on the core with neighboring pin members connected to each other. A first pin member and a second pin member both adjacent to each other have a welded part in which an end face of an end part of the first pin member and a peripheral surface of an end part of the second pin member are welded to each other. A width of a part, of the first pin member, except the welded part is smaller, as viewed from a direction along a center line of the end part of the second pin member, than a width of a part, of the second pin member, except the welded part.

A first pin member and a second pin member both adjacent to each other have a welded part in which an end face of an end part of the first pin member and a peripheral surface of an end part of the second pin member are welded to each other. The welded part is not provided on an outer side edge of the second pin member as viewed from a direction orthogonal to a first plane containing a center line of the end part of the first pin member and a center line of the end part of the second pin member.

Abstract: An inductor component includes an annular core; and a first coil and a second coil that are wound around the core so that winding axes thereof are parallel to each other. The first coil and the second coil each include a conductor portion and a coating that covers the conductor portion. The inductor component further includes a first insulating resin that covers at least a part of the conductor portion of the first coil, the part being exposed from the coating; and a second insulating resin that covers at least a part of the conductor portion of the second coil, the part being exposed from the coating. The first insulating resin and the second insulating resin are not connected but separated in a space between surfaces of the first coil and the second coil that face each other.

Abstract: An inductor component includes a core having an annular shape; an insulating member that covers a portion of the core; a coil wound around the core and the insulating member; and a buffer member that is elastic. The core has a first face, a second face that crosses the first face, and a third face that faces the second face and crosses the first face. The insulating member is provided to cover the first face, a portion of the second face, and a portion of the third face. The core and the insulating member are bonded to each other with the buffer member interposed therebetween.

An inductor component includes an annular core; and a coil including a plurality of pin members and wound on the core with neighboring pin members connected to each other. A first pin member and a second pin member both adjacent to each other have a welded part in which an end part of the first pin member and an end part of the second pin member are welded to each other, and the end part of the second pin member has a constricted part whose width is narrower.
