    • PROBLEM TO BE SOLVED: To improve current measurement accuracy in a current measurement device having a current measurement section formed with a plate-shaped resistor. SOLUTION: A first electrode 111 of the current measurement section formed by a multilayer substrate and a resistor 121 are connected with a plurality of round-hole-shaped first through-holes 101a, and the resistor 121 and a second electrode 131 are connected with a plurality of round-hole-shaped second through-holes 101b. Further, all first through-holes 101a and all second through-holes 101b are connected with a voltage sensor for current measurement, respectively. Thus, even if current flowing in the plate-shaped resistor 121 does not uniformly flow, current measurement accuracy of the current measurement device can be improved by restraining a generated potential difference of a potential difference detection means 102 from generating a measurement error.
