Abstract: A current sensor has a chassis, a magnetism detection element, and a bus bar through which a current under measurement flows. The current sensor is mounted on a circuit board in a state in which the chassis is inserted into an opening formed in the circuit board with current paths provided on a mounting surface and the bus bar is connected to the current paths. The bus bar has an incorporation portion placed in the interior of the chassis as well as externally connected portions extending from both ends of the incorporation portion, one from each side, toward the outside of the chassis. The externally connected portions are positioned above the bottom surface of the chassis in the up-down direction. The incorporation portion has an underneath portion positioned below the externally connected portions in the up-down direction.
