Patent ID: 7277001

Claim:
A coil-embedded dust core comprising: a molded coil component including a coil main body having an edgewise winding structure in which a flat type conductor wire having a flat portion is wound in such a way that the flat portion is arranged substantially perpendicularly to a winding axis, wherein one end side terminal portion is disposed by leading an end portion of the flat type conductor wire located on the one end side of the coil main body in parallel to the winding axis of the coil main body, the other end side terminal portion disposed by leading an end portion of the flat type conductor wire located on the other end side of the coil main body in parallel to the winding axis of the coil main body, wherein one end side leading electrode portion is disposed by extending the one end side terminal portion, and the other end side leading electrode portion is disposed by extending the other end side terminal portion; a dust core composed of a soft magnetic alloy powder compact disposed covering the coil main body, the one end side terminal portion, and the other end side terminal portion of the molded coil component; wherein the one end side terminal portion and the other end side terminal portion are extended to one surface or the other surface of the dust core, the surfaces being perpendicular to the winding axis direction of the coil main body; and wherein the one end side leading electrode portion that is extended from the one end side terminal portion lead to the one surface or the other surface of the dust core is extended along the dust core surface to a corner portion side of the dust core, and is bent so that the one end side leading electrode portion is exposed.
