Abstract
A nonreciprocal circuit device is provided which prevents the center conductors thereof from interfering with each other when folded toward a magnetic body even when the magnetic body has a rectangle shape in plan view, and which thereby increases the reliability of the bonding portion between the center conductor coupling portion and capacitors or input/output terminals, and a communication device using the same is further provided. A ferrite having a rectangle shape in plan view is placed on the coupling portion of the center conductors, and a magnetic assembly is constructed by folding the center conductors extending from the coupling portion outward so as to wrap the ferrite. At this time, the port portions of the center conductors extending from the coupling portion outward substantially line-symmetrically are formed asymmetrically with each other so as not to mutually interfere when these center conductors are folded toward the magnetic body.
