Claims

[Scope of utility model registration request]

(1) A fixed inductor characterized in that an electrode is formed by a plate-shaped metal piece that is inserted between the flanges at both ends of the winding portion of the core from above and below, and a lead of the winding is connected to the electrode. .

(2) A stepped portion is formed on the surfaces of the tsuba at both ends that are sandwiched between the electrodes, and as the tsuba is inserted into the stepped portion, the surface of the electrode between the tsuba surface and the nucleus is approximately the same. The fixed implant according to claim 1 of the utility model registration located in the same horizontal position.

(3) The fixed inductor according to claim 1, wherein a resin mixed with an oxide magnetic material is located inside the electrode.

(4) A metal film is formed on the surface of the collar at both ends sandwiched in the electrode, and the electrode and the winding lead are connected to the metal film as described in claim 1 of the utility model registration claim. fixed inductor.
