Claims

[Scope of utility model registration request]

Two C-shaped cores with wire wound and attached to a holder are joined by screwing the holders together, a magnetic head element with a magnetic gap formed at the joint is housed in a shield case, and the shield case is embedded and filled with resin. In the ring-shaped magnetic head, an inverted U-shaped leaf spring having convex side surfaces on both sides and a rectangular cutout on the top surface is provided, and the core head and holder shoulder of the magnetic head element are attached to the rectangular cutout of the leaf spring. After inserting the magnetic head element into the shield case, place the convex side surfaces of the leaf spring in the gap between the magnetic head element and the shield case on both sides, press the magnetic head element into the shield case via the leaf spring, and adjust the position. A ring-shaped magnetic head characterized by being constructed by filling resin after being held.
