Abstract
A core for a wire-wound electronic component. The core has a winding base to be wound with a wire, and flanges located at both ends of the winding base in an extending direction of the winding base. The flanges protrude from the winding base in a first direction perpendicular to the extending direction. Each of the flanges has a plurality of protrusions on a first surface at a side of the flange in the first direction. An inclined surface is provided to extend from the first surface of each of the flanges to a second surface of the winding base at a side of the winding base in the first direction.

A core for a wire-wound electronic component, the core comprising:
- a winding base to be wound with a wire;
- and
- flanges located at both ends of the winding base in an extending direction of the winding base and protruding from the winding base in a first direction perpendicular to the extending direction,
- each of the flanges having a plurality of protrusions on a first surface at a side of the flange in the first direction, and
- an inclined surface formed on the first surface of each of the flanges, in an area extending from a space between the plurality of protrusions to a second surface of the winding base at a side of the winding base in the first direction, so as to be inclined to the second surface.
A core for a wire-wound electronic component, the core comprising:
- a winding base to be wound with a wire;
- flanges located at both ends of the winding base in an extending direction of the winding base and protruding from the winding base in a first direction perpendicular to the extending direction, at least one of the flanges having a first protrusion and a second protrusion on a first surface at a side of the flange in the first direction, the first protrusion and the second protrusion being arranged with a space therebetween in a second direction perpendicular to the first direction and the extending direction;
- and
- an inclined surface extending from the first surface to a part of a second surface of the winding base, the second surface being located at a side of the winding base in the first direction, wherein
- with respect to the extending direction, the first surface lies between the inclined surface and the first and the second protrusions, such that the inclined surface does not contact the first and second protrusions, and
- the inclined surface and the second surface are at an obtuse angle to each other when viewed from the second direction perpendicular to the first direction and the extending direction.
A wire-wound electronic component comprising:
- a core for the wire-wound electronic component, the core comprising:
- a winding base to be wound with a wire;
- flanges located at both ends of the winding base in an extending direction of the winding base and protruding from the winding base in a first direction perpendicular to the extending direction, at least one of the flanges having a first protrusion and a second protrusion on a first surface at a side of the flange in the first direction, the first protrusion and the second protrusion being arranged with a space therebetween in a second direction perpendicular to the first direction and the extending direction;
- and
- an inclined surface extending from the first surface to a part of a second surface of the winding base, the second surface being located at a side of the winding base in the first direction, wherein
- with respect to the extending direction, the first surface lies between the inclined surface and the first and the second protrusions, such that the inclined surface does not contact the first and second protrusions,
- the wire;
- and
- external electrodes provided on the respective protrusions, wherein the wire extends on the inclined surface.
