SOLUTION: When an instruction peak value is below a predetermined voltage, application control for controlling a voltage application circuit 22 so that the voltage the polarity of which is periodically inverted is applied to the sample, on the basis of the instruction peak value is performed using a third frequency, which is higher than a first frequency, as a polarity inversion frequency and using a second frequency as a carrier frequency, and using a conversion value obtained from a breakdown period from the start of control to the breakdown of the sample and the ratio of the third frequency to the first frequency, the insulating performance of the sample is evaluated. When the instruction peak value is the predetermined voltage or higher, the application control is performed by using the first frequency as the polarity inversion frequency and using a fourth frequency which is higher than the second frequency as the carrier frequency; and by using a conversion value obtained from the breakdown period and the ratio of the fourth frequency to the second frequency, the insulating performance of the sample is evaluated.
