する高周波コイル。 A high-frequency coil consists of a bobbin or drum core placed on a substrate, a wire wound thereon, a movable core for inductance adjustment that covers the winding portion, a core holder that screws and holds it, and a shield case that houses all of these. A vertical slit is provided along the entire length of one side of the shield case, and when the core holder is molded with resin, the shield case is inserted into the mold and then insert molded.
This high-frequency coil features a structure in which the longitudinal slit is also filled with resin and the core holder and shield case are integrated.
