Claims

[Scope of utility model registration request]

A ferrite assembly is constructed by placing a dielectric substrate on which an impedance matching electrode film is formed on a ground plate placed on the bottom wall of a magnetic case body, and by placing ferrites facing a plurality of center conductors. In the non-reciprocal circuit element configured to connect the lead-out portions of the center conductors to the impedance matching electrode film, a recess is formed in the side wall of the case body, and a recess is formed on the edge of the recess. A mating claw portion is integrally formed, a resin pressing member is arranged on the dielectric substrate of the case body, a fitting protrusion that fits into the recess is integrally formed on the pressing member, and the fitting protrusion engages the engaging claw portion, thereby pressing the dielectric substrate with the pressing member onto the bottom wall of the case body via the ground plate,
A non-reciprocal circuit element characterized in that a lead-out portion of each of the center conductors is connected to the impedance matching electrode film.
