    摘要： A non-reciprocal circuit element includes a magnetic plate, a common electrode, a first main segment, a second main segment, a third main segment, and a magnet opposing to the magnetic plate and the magnet applying a bias magnetic field. The temperature coefficient of the saturation magnetization of the magnetic plate is from −0.2%/° C. to −0.1%/° C. in the temperature range from −35° C. to 85° C. The temperature coefficient of the residual magnetization of the magnet is from −0.20%/° C. to −0.15%/° C. in a temperature range from −35° C. to 85° C.
