摘要： This element can be miniaturized irrespective of the value of the matched capacitance. A circulator (1) is provided with a multilayered board (3) for forming a central electrode (16a) and matching capacitance. The multilayered board (3) is produced by laminating a plurality of dielectric sheets on which the central electrode or the matching capacitance electrode is formed, and burning them integrally. The matching capacitor is structured by connecting in parallel the capacitors formed by laminating many numbers of dielectric sheet pinched by a pair of capacitor electrodes. On the upper surface of the multilayered board (3), there are formed in positions facing the central electrode (16a) a first recess (26) for receiving ferrite (4), and a second recess (25) for receiving a permanent magnet (5). In these recesses, the ferrite (4) and the permanent magnet (5) are installed, respectively.
