PROBLEM TO BE SOLVED: To accurately measure the effective value on a contact current of an AC waveform on which a DC component is superimposed. SOLUTION: A processing part 7 executes: a measuring processing for measuring a DC component Idc and an AC component Iac from waveform data D1 of a contact current Itc flowing in a human body simulation circuit 2; an effective value calculation processing for calculating q sinusoidal wave effective value Iev of the contact current Itc, by dividing a swinging width Ipp of the contact current Itc calculated from the waveform data D1 by a value (2×√2), when each component Idc, Iac is equal to or more than each reference value Ir1, Ir2 together, and a duration T1 of the contact current Itc is over m times a cardiac cycle Tc, and calculating a sinusoidal wave effective value Iev, by dividing the maximum absolute value Ip of a peak value of the contact current Itc calculated from the waveform data D1 by a value of Ip/√2, when each component Idc, Iac is equal to or more than each reference value Ir1, Ir2 together, and the duration T1 is below n times the cardiac cycle Tc; and an output processing for outputting the sine wave effective value Iev to an output part 10.
