Abstract
A current sensor for measuring a current flowing through a conductor includes a sensor substrate, a magnetoelectric converter formed on a surface of the sensor substrate and configured to output a signal changing with an applied magnetic field, and a magnetic shield that surrounds the sensor substrate and the conductor to magnetically shield the inside from the outside. The output signal of the magnetoelectric converter changes with a magnetic filed applied along the formation surface of the sensor substrate. The magnetic shield has at least one gap for reducing magnetic saturation in the magnetic shield. The gap and the sensor substrate are located at the same height in a z-direction orthogonal to the formation surface of the sensor substrate.
