Summary:A method for deriving an equivalent circuit model of a capacitor which makes it possible to derive, with high accuracy and with ease, an equivalent circuit model having characteristics in accordance with a direct current voltage applied to a capacitor. Characteristic values of predetermined resistive elements and capacitive elements forming an equivalent circuit model of a capacitor change in response to a DC bias voltage being applied to the capacitor, and the change is attributable to the material of a dielectric forming the capacitor. However, by multiplying the characteristic values of the resistive elements and the capacitive elements held while the DC bias voltage is not applied by a dimensionless coefficient in accordance with an application rule, the characteristic values of the resistive elements and the capacitive elements are corrected to values in accordance with the voltage of the DC bias voltage applied to the capacitor.
