Abstract
A current sensor includes: a magnetic core member including a core main body obtained by forming a slit-shaped gap portion along a tube axis direction in a tube that surrounds a conductive member, which is an object to be energized, on an inner side with a clearance, the magnetic core member being configured to generate a magnetic flux corresponding to a current flowing through the conductive member; a magnetic sensor configured to output a signal corresponding to magnetic flux density in the gap portion; and a magnetic shield member including a shield main body that surrounds the core main body from an outer side of the core main body with a clearance, the magnetic shield member being configured to block magnetism between inside and outside of the shield main body by the shield main body.
