Abstract

A current sensor includes at least three bus bars made of flat-plate-shaped conductors and an inverter, a plurality of cores in which a core is formed by stacking flat plates made of U-shaped magnetic bodies, and a detecting element arranged on the side of an opening portion of each of the cores for detecting the intensity of a magnetic field. An interval between the core and another bus bar that is adjacent to the bus bar inserted into the U groove of the core is ½ of the length of the opening portion in the spacing direction, and the tolerance of the gap is set to a value obtained by subtracting the value of 3/2 of the length of the opening portion in the spacing direction from the value of the interval between the bus bars that are adjacent to each other, with the gap as a median value.
