摘要： Provided is a center conductor assembly for an irreversible circuit element. The center conductor assembly includes at least one center conductor constituting a first inductance element and a second center conductor constituting a second inductance element. The first center conductor and the second center conductor are formed on a layered body having a plurality of magnetic layers as a unitary block. The first center conductor connects a first and a second line formed on the first main surface of the layered body to a third line formed inside the layered body, by using a via hole. The second center conductor is formed on the first main surface of the layered body so as to intersect the third line between the first and the second line via a magnetic layer.

摘要： An irreversible circuit element in which manufacturing process is simplified and insertion loss is reduced, and its manufacturing method and a communication apparatus. The irreversible circuit element (two port type isolator) comprises a ferrite/magnet assembly where a first central electrode (35) and a second central electrode (36) are formed of a conductive film on the major surfaces (32a, 32b) of a ferrite (32) while being insulated from each other and intersecting each other, and the ferrite (32) is sandwiched by a pair of permanent magnets having a major surface identical to that of the ferrite (32). Recesses formed in the upper and lower side faces (32c, 32d) of the ferrite (32) are filled with a conductor material to form interconnecting electrodes (35a, 36b, 36f, 36j, 36m, 36d, 36h, 36l) and connecting electrodes (35b, 35c, 36p).
