Abstract
A current sensor includes units each of which has a bus bar through which current flows, a magnetic sensor facing one of plate surfaces of the bus bar, a shield facing the other plate surface. The units have a large-current unit and a small-current unit. A first distance between the bus bar and the magnetic sensor in a normal direction of the plate surfaces of the bus bar is the same as a distance L1A of the large-current unit and a distance L1B of the small-current unit. Since, as for a second distance between the bus bar and a base of the shield, a distance L2A of the large-current unit is larger than a distance L2B of the small-current unit, a measurement range of the large-current unit is widened and a measurement error due to magnetic saturation of the shield is suppressed.
