A current detector includes a magnetic core that is molded by sintering powder made from a magnetic material, and a current detection busbar. The current detection busbar is a conductor including a penetrating portion that penetrates a hole portion of the magnetic core in a first direction in which a current flows, and terminal portions that are in connection with the penetrating portion on both sides in the first direction. The width of the terminal portions is larger than the maximum width of the hole portion, and the minimum width of the cross-sectional contour of the penetrating portion is larger than the thickness of the terminal portions. An insulating casing holds the magnetic core, the current detection busbar, and the Hall element, while keeping them from coming into contact with each other. |
