A non-reversible circuit element having a simple structure, stable electric characteristics, and a high reliability. The non-reversible circuit element (two-port type isolator) comprises a flat plate yoke (10), a permanent magnet (41), a ferrite (32) to which DC magnetic field is applied by the permanent magnet (41), a first center electrode and a second center electrode disposed in the ferrite (32), and a circuit board (20). The flat plate yoke (10) is placed on the upper surface of a ferrite-magnet assembly (30) through a dielectric layer (15). The dielectric layer (15) is an adhesive agent layer made of, for example, an epoxy resin. |
