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.

Abstract: An inductor component includes a bottom plate portion that includes a first main surface and a second main surface; an annular core that is disposed on the bottom plate portion; a coil that is wound around the core; and an electrode terminal that is attached to the bottom plate portion and electrically connected to the coil. The electrode terminal includes a mounting surface portion configured to connect to a mount substrate. The core is disposed on the first main surface of the bottom plate portion so that an axis of the core intersects the first main surface of the bottom plate portion. The mounting surface portion is exposed on the second main surface side of the bottom plate portion, and at least a part of the mounting surface portion overlaps the core when seen in a direction perpendicular to the first main surface of the bottom plate portion.

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: A common mode choke coil includes a core, and first and second coils opposed to each other and wound on the core. The core can have a square shape, or an elongated shape having a long axis and a short axis when viewed in a direction along a central axis of the core. Each of the first and second coils is a single-layer coil. An area of a cross-section of the core taken perpendicular to a circumferential direction of the core is constant in the circumferential direction of the core. The cross-section of the core has a quadrilateral shape.

Abstract: In an inductor component, an inductor wire is formed inside a main body. The inductor wire has a circular columnar body extending in the height direction. An end surface of the inductor wire at a first end in the wire extending direction serves as a first external terminal and is exposed at a first terminal surface of the main body. The first external terminal is exposed only at the first terminal surface. An end surface of the inductor wire at a second end in the wire extending direction serves as a second external terminal and is exposed at a second terminal surface of the main body. The second external terminal is exposed only at the second terminal surface.

Abstract: An inductor component includes a case; an annular core accommodated in the case; a coil wound around the core; and an electrode terminal attached to the case and connected to the coil. The electrode terminal includes a mounting surface portion that is disposed along an end surface of the core and that is to be mounted on a mount substrate, and a connection surface portion that is perpendicularly connected to the mounting surface portion and that is disposed along an outer peripheral surface of the core. The coil includes a plurality of pin members including a first linear pin member. A connection surface that is a part of an outer peripheral surface of the first linear pin member is in surface-contact with a first main surface of the connection surface portion in a state in which the connection surface is positioned parallel to the first main surface.
