Claims

[Scope of utility model registration request]

A first flange is integrally formed at one end of the magnetic core, a second flange made of a resin material is fitted and fixed to the other end of the magnetic core, and the magnetic core is formed from the periphery of the second flange. A kerf is formed that reaches the circumferential surface of the magnetic core in the axial direction, and the winding guided by the kerf is wound around the circumferential surface of the magnetic core. Winding frame for coils.
