Abstract
In a current detection device, a first shield plate is disposed adjacent to a magnetic sensor and a second shield plate is disposed adjacent to the bus bar so that the first and second shield plates sandwich the bus bar and the magnetic sensor in the thickness direction of the bus bar. A plurality of the first shield plates adjacent to the magnetic sensors are an integral part of a cover. At least part of the cover is separated between adjacent two of the first shield plates, and a plurality of the second shield plates disposed adjacent to the bus bars are an integral part of a casing.
