Abstract
An equivalent circuit includes a first capacitor having a first capacitance, a circuit part configured to include an inductor component, a capacitor component, and a resistor connected in series with one another, the circuit part being connected in parallel with the first capacitor, and a second capacitor provided between the first capacitor and the circuit part and having a second capacitance. The first capacitance of the first capacitor changes in accordance with a voltage value of a direct current voltage applied to the first capacitor. The second capacitor has the positive second capacitance that changes in accordance with the voltage value of the direct current voltage applied to the first capacitor and that is N times (N>0) the first capacitance of the first capacitor.
