PROBLEM TO BE SOLVED: To solve the problem wherein normality or abnormality of a small capacity of capacitor C2 cannot be determined in an analog circuit 14 which is juxtaposed with a large capacity of capacitor C1 and the small capacity of capacitor C2, even if inspecting the combined capacity. SOLUTION: A spike-like voltage waveform having a prescribed frequency is input into a signal line connected with the capacitor C2 from a signal generation means 2. The normality or abnormality of the capacitor C2 can determined by confirming whether the spike-like voltage waveform is remained in a signal v2 output from the analog circuit 14 by using a counting means 6 and a determination means 8, because the frequency of the spike-like voltage waveform is set in a removable frequency band, when the capacitor C2 is normal. The individual capacitor can be inspected using the spike-like voltage waveform set in each frequency band, when the removable frequency bands are different from each other, when juxtaposing in parallel the capacitor C1 and the capacitor C2.
