A current sensor has two magnetic shields, a target current path, an adjacent current path, and a magneto-electric conversion element. The target current path includes a target partial current path positioned in a spacing. The adjacent current path includes an adjacent partial current path separated from the target partial current path at least in a first direction. Each magnetic shield includes a near end positioned on the same side as the adjacent partial current path in the first direction. In the first direction, the magneto-electric conversion element is positioned between the near end and the center position of the magnetic shield in the first direction.
