Abstract
In a non-reciprocal circuit element, the characteristics variation with respect to temperature is suppressed with a simple configuration without changing a magnetic material or the material of a magnet. A non-reciprocal circuit element includes: a magnetic material () to which a DC magnetic field (G) is applied; a plurality of center electrodes () disposed on the magnetic material () so as to intersect each other in an insulated state; a terminal resistor (R) connected between input and output ports (P, P) and in in parallel with one of the center electrodes (); a variable capacitance element (C) connected between the input and output ports (P, P) and in parallel with the terminal resistor (R); and a thermistor element (S) connected to a control power supply circuit (E) of the variable capacitance element (C) and in series with the variable capacitance element (C).
