Claims

[Scope of utility model registration request]

(1) A coil bobbin with a small-diameter outer flange and a large-diameter outer flange at both ends, and a pair of terminals protruding from the outer surface of the large-diameter outer flange, and a coil bobbin that is wound around the body of the coil bobbin and has both ends connected to the terminals. A high-frequency coil comprising windings connected to each other, and a cap that is fitted from the small-diameter outer flange side of the coil bobbin and whose opening side end is fixed to the large-diameter outer flange.

(2) The high-frequency coil according to claim (1), wherein the coil bobbin and the cap are each made of a magnetic member.

(3) The cap has the opening edge of the opening side end surface fixed to the inside edge of the large diameter outer flange, and a ring-shaped hem piece that covers the large diameter outer flange is protruded from the outer periphery of the opening side end surface. Utility model registration claim 1 or 2, in which the tip of the hem piece protrudes outward beyond the outer surface of the large-diameter outer flange.
The high frequency coil described in section 2).

(4) Utility model registration claim no. 3)
High frequency coil as described in section.

(5) The high-frequency coil according to claim (4), wherein the notch is an L-shaped notch with a vertical side extending in the axial direction of the cap and a horizontal side extending in the circumferential direction of the cap.
