Abstract:
1. A nonreciprocal circuit element comprising: a magnetic plate having a plurality of through holes; a plurality of center conductors crossing each other at a predetermined angle on a side associated with a first surface of the magnetic plate; and a common electrode disposed on a side associated with a second surface of the magnetic plate and connected to the center conductors via the through holes, wherein capacitors connected to first ends of the center conductors are disposed on the side associated with the first surface of the magnetic plate, and a case is formed by a first yoke disposed on the side associated with the first surface of the magnetic plate, and a second yoke disposed on the side associated with the second surface of the magnetic plate so as to also function as a grounding electrode, the capacitors being connected to the second yoke via other through holes provided in the magnetic plate.
