Abstract
A current sensor includes a busbar extending in a direction, a magnetic sensor facing the busbar in a direction intersecting the direction in which the busbar extends, a magnetic shield having a base that faces the busbar, at least a portion of the base facing a side of the busbar opposite to a side where the magnetic sensor is disposed, and a case having an insert-molded section in which at least a part of the magnetic shield is insert-molded. The insert-molded section has holes (first holes), and in the holes (first holes), some portions of the magnetic shield are exposed as exposure portions (first exposure portions) and the exposure portions (first exposure portions) have rust-prevention properties. Such a current sensor has the rustproofed exposure portions and thus problems caused by rusting in the exposure portions in the magnetic shield can be prevented or reduced.
