Abstract

PURPOSE:To attain miniaturization by providing a permanent magnet ouside of one soft magnetic body and by using one terminal of a center conductor as a strip line teminal for a cnnection with an external circuit. CONSTITUTION:On a soft magnetic body 12, a ferrite core 6b is arranged via a shield plate 15b. On the core 6b, three center conductors 13a-13c are mounted with their crossing parts insulated from one another. Further, a ferrite core 6a is mounted on those conductors and then covered with another shield plate 15a. A permanent magnet 3 is arranged on the shield plate 15a with a soft magnetic body 11 between. The conductors 13a-13c, when built up, project out of a circulator, and the projecting parts are used as strip line terminals. Thus, the circulator is made extremely compact without excessive space.
