ELECTRICAL CURRENT METER, ELECTRICAL CURRENT METER FOR DISTRIBUTION BOARD, DISTRIBUTION BOARD, AND PRODUCTION METHOD FOR ELECTRICAL CURRENT METER

摘要

The present invention addresses the problem of increasing the accuracy with which a load current is measured. This electrical current meter (5) comprises a measurement unit (55) that is provided with a semiconductor chip (551), a plurality of electrodes (552), and a plurality of leads (553) that are arranged so as to be aligned along a predetermined direction. The plurality of leads (553) comprises a pair of input leads (558, 559) into which an output signal from a coil is input. The plurality of electrodes (552) comprises a pair of input electrodes (556, 557) that are electrically connected to each of the pair of input leads (558, 559). Each of the pair of input leads (558, 559) has one of the ends of a wire (554) connected thereto at positions that are offset from each other in a direction that leads from the center of a predetermined direction toward each of said input leads (558, 559).
