PROBLEM TO BE SOLVED: To enhance measurement accuracy, and measure an electric current value of a measurement electric current on the basis of a frequency component included in a desired frequency band.SOLUTION: A current probe CP used while being mounted to common measurement object electric wire 2 comprises: a plurality of input parts 11a to 11c that is capable of connecting a plurality of current probes CP1 to CP3 one by one consisting of one current sensor CS1 to CS3 mutually different in a detection frequency band; a signal addition part 14 that adds an added amount based upon detection signals Vi1 to Vi3 to be output from the plurality of current probes CP1 to CP3 connected to each input part 11a to 11c, and outputs the added amount as an addition signal (addition waveform data Dad showing a signal waveform of the addition signal); and a processing part 15 that calculates an electric current value I1 of a measurement electric current I running through the measurement object electric wire 2 on the basis of the waveform data Dad. |
