Claims

[Claims for Utility Model Registration] (1) A flange is provided at at least one end in the axial direction of a coil winding frame formed in a cylindrical shape with an inner diameter portion serving as a core insertion hole; A pin terminal is implanted on the outer end surface of the flange, a core insertion groove is provided inside the pin terminal and continues to the inner diameter portion of the coil winding frame, and the core insertion groove is provided on the outer end surface of the flange. 1. A coil bobbin comprising a pair of protruding stripes having substantially the same height that are sandwiched and facing each other, wherein opposing surfaces of the protruding stripes are inclined surfaces in which the distance between the surfaces increases toward the tip. (2) The coil bobbin according to claim 1, wherein the inclined surface is continuous with the protrusion from the middle of the inner wall surface of the core insertion groove.
