<p>The purpose of the invention is to reduce, in a non-reciprocal circuit element, the inductance of a second center electrode without causing other adverse effects, and to make actuation possible in a high frequency band. A non-reciprocal circuit element provided with: a permanent magnet; a microwave magnetic body (32) to which a DC magnetic field is applied by the permanent magnet; a first center electrode (35) which is wound on the microwave magnetic body (32) and which has one end connected to an input port (P1) and the other end connected to an output port (P2); a second center electrode (36) which is wound on the microwave magnetic body (32) so as to intersect the first center electrode (35) while being insulated, the second center electrode (36) having one end connected to the output port (P2) and the other end connected to a ground port (P3); a first matching capacitor (C1) connected in parallel to the first center electrode (35) between the input port (P1) and the output port (P2); a terminal resistor (R) connected in parallel to the first center electrode (35) between the input port (P1) and the output port (P2); and a second matching capacitor (C2) connected between the output port (P2) and the ground port (P3). A sub-center electrode (37) is connected in parallel to a part of the second center electrode (36).</p> |
