PROBLEM TO BE SOLVED: To provide a current measuring device capable of improving the reproducibility of the current waveform. SOLUTION: The current measuring device comprises the sampling means 1 for collecting the sampling value of the current with a predetermined sampling period, the acquisition range setting means 2 for setting the acquisition range, the sampling value memory means 3 for storing the sampling value from entering the sampling value acquisition range to the out going from the range, the representative sampling period calculation means 4 for calculating the representative sampling period by dividing the sampling number by previously set representative sampling numbers, the representative sampling value extracting means 5 for extracting the representative sampling value from the sampling value at the every sampling period, the maximum current value detection means 6 for detecting the maximum current value from the sampling value, and the final sampling value memory means 7 for storing the maximum current value and the representative sampling value.
