Claims

[Claims for Utility Model Registration] 1. A dielectric substrate with a circulator pattern formed on its surface, a ferrite disk placed on the junction of the circulator pattern, and the dielectric material provided on the ferrite disk. A non-reciprocal circuit element comprising: a highly conductive plate that is connected to a ground pattern of a substrate and serves as a ground conductor; and a permanent magnet that applies an external magnetic field to the junction part. 2. In the non-reciprocal circuit element according to claim 1, a front-side ground pattern that is electrically connected to the back-side ground pattern is formed around the circulator pattern on the surface of the dielectric substrate, and the good conductive plate has L in three directions. A circulator which is an integrally formed metal plate having an angled support leg, the tip of the support leg being soldered to the surface-side ground pattern. 3. The non-reciprocal circuit element according to claim 1, wherein a dummy resistor is provided at one terminal of the circulator pattern formed on the surface of the dielectric substrate, and the other end of the dummy resistor is connected to the ground pattern. 4 A front-side ground pattern that is electrically connected to the back-side ground pattern is formed on both ends of the dielectric substrate surface, and the good conductive plate is a metal integrally formed so that it has L-angle-shaped support legs at both ends. 4. The isolator according to claim 3, wherein the isolator is a plate, and the tips of the supporting legs are soldered to the surface-side ground pattern. 5. The non-reciprocal circuit element according to claim 1, wherein the permanent magnet is bonded on the highly conductive plate.
