Abstract
A current sensor includes a magnetic detection element that senses a magnetic flux generated from a current path to perform electromagnetic conversion, and at least two magnetic shields that are arranged around the magnetic detection element and shield an external magnetic flux affecting the magnetic detection element. The at least two magnetic shields include a first magnetic shield and a second magnetic shield facing each other across the magnetic detection element and the current path. At least one of the first magnetic shield and the second magnetic shield includes at least two base portions and a coupling portion coupling the at least two base portions. The at least one of the first magnetic shield and the second magnetic field has a recess recessed from a periphery in a surface facing the other of the first magnetic shield and the second magnetic shield.
