Abstract
A current sensor includes a magnetic sensor configured to detect a magnetic field generated by a current to be measured flowing through a current path and a shielding member including a first shield, a second shield, and a third shield disposed away from each other. The first shield is disposed on an opposite side of the current path from the magnetic sensor in a first direction in which the magnetic sensor and the current path oppose each other and includes a first opposing surface opposing the current path. The second shield includes a second opposing surface along the first direction. The third shield includes a third opposing surface along the first direction. The second shield and the third shield are disposed such that the second opposing surface and the third opposing surface oppose each other, with the magnetic sensor and the current path sandwiched therebetween.
