Abstract

A nonreciprocal circuit device which can be miniaturized, and can achieve low insertion loss, having plate-like capacitors disposed vertically. Single plate capacitors are arranged vertically so that their electrode faces are at an angle of 90 degrees to a ferrite, and in addition, their bottom faces are at a position above the bottom half of the thickness of the ferrite, or more preferably, at a position higher than the top face of the ferrite.
