CURRENT MEASURING DEVICE, DISTRIBUTION BOARD CURRENT MEASURING DEVICE, DISTRIBUTION BOARD, AND MANUFACTURING METHOD OF CURRENT MEASURING DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a current measuring device, a distribution board current measuring device, and a distribution board which can improve calculation accuracy of load current, and a manufacturing method of the current measuring device.SOLUTION: A measurement unit 55 of a current measuring device 5 comprises: a semiconductor chip 551; a plurality of electrodes 552; and a plurality of leads 553 arranged along a first direction. The leads 553 include a pair of input leads 558, 559 into which an output signal of the coil 52 (as referred to Fig. 3) is inputted. The electrodes 552 include a pair of input electrodes 556, 557 which are respectively and electrically connected with the input leads 558, 559. One end of each wire 554 of the input leads 558, 559 is connected to a position deviated from the center of the first direction so that the input leads 558, 559 become closer each other.
