    摘要： A high-frequency use non-reciprocal circuit includes a sintered body which is a high-frequency use magnetic body obtained by a ceramic lamination/integral firing technique, a plurality of central electrodes which are arranged in the sintered body to be separated from each other through a magnetic layer while intersecting with each other at central portions, and electrodes for deriving impedance-matching capacitance which are formed in the vicinity of the intersecting portion to be in series with the central electrodes. The magnetic layer provided between the central electrodes serves as an insulating layer for electrically insulating the central electrodes from each other, a high-frequency use magnetic layer, and a material layer for deriving the impedance-matching capacitance.
