Patent ID: 8736412

Claim:
A magnetic element, comprising: a first core member having a pair of flange parts constituted of one flange part and another flange part, a columnar part coupling the pair of flange parts, and a winding frame part surrounded by the pair of flange parts and the columnar part; a second core member disposed to face the first core member along an entire outer periphery thereof; a coil disposed on the winding frame part by winding a lead wire; and a base shaped body on which the one flange part of the first core member is placed and on which the second core member is placed on an outer peripheral side with respect to the first core member, wherein the base shaped body is provided with a base member and a terminal member partially embedded in the base member, the terminal member is provided with a binding terminal part, which projects outward in a second corner part out of plural corner parts of the base member and projects from the base member on a side separated along an axial direction of the columnar part from a portion of the winding frame part side of the one flange part, and to which an end of the lead wire is bound, a user terminal part in a state integrated with the binding terminal part and the user terminal is electrically connected to an external mounting substrate, and a forming terminal part in a state integrated with both the binding terminal part and user terminal part, and the second core member is provided with a cutout part at a portion corresponding to the second corner part of the base member for allowing insertion of an end of the lead wire drawn out from the winding frame part in a state of not contacting the second core member; further, the second core member is provided in a substantially rectangular shape and cut off parts are provided on at least two corners of the second core member forming the substantially rectangular shape which is cut off at an angle with respect to wall faces forming these corners, the forming terminal part is provided with a vertical extending portion and a horizontal extending portion continuing to the vertical extending portion, the vertical extending portion extends along an outer wall face of the second core member and along a first corner part out of plural corner parts, and the horizontal extending portion is bent from the vertical extending portion so as to be facing and contacting a face of the another flange part opposite to the winding frame part and a portion of the second core member opposite to the side placed on the base member.
