Abstract:
1. A non-reciprocal circuit element in which a central conductor in the form of a flat plate in which respective resonators extending outward are formed between I/O terminals extending outward and radially from a central portion in three directions, upper and lower ferrite plates between which the central conductor together with the resonators is sandwiched, and upper and lower magnetic metal plates between which the upper and lower ferrite plates are sandwiched are stacked, a magnet is arranged on the upper magnetic metal plate, and the upper and lower magnetic metal plates form a closed magnetic circuit via a side plate, wherein bent portions which are bent in out-of-plane directions and form an interstice between the central conductor and the upper ferrite plate and/or the lower ferrite plate are formed at respective distal end portions of the resonators of the central conductor such that the upper ferrite plate and/or the lower ferrite plate is provided to be capable of coming into and out of contact with the central conductor due to elasticity of the bent portions.
