Patent attributes
A current sensor includes an electrical-conduction member, a magnetoelectric converter, and a shield. The shield includes a first shield and a second shield each having a plate shape. The first shield and the second shield being arranged such that surfaces are opposed to and spaced away from each other. A part of the electrical-conduction member and the magnetoelectric converter are located between the surface of the first shield and the surface of the second shield. The part of the electrical-conduction member extends in an extension direction that is along the surface of the first shield. At least one of the first shield and the second shield has an anisotropy in magnetic permeability in which the magnetic permeability in a lateral direction that is along the surface of the first shield and perpendicular to the extension direction is higher than the magnetic permeability in the extension direction.
