Abstract
A current sensor, which is configured to individually detect a current flowing in each of at least two current paths, includes at least two phases. Each phase includes a magnetic field detection element and a pair of first magnetic shield and second magnetic shield. The magnetic field detection element is disposed to face one of the current paths. The magnetic field detection element is configured to detect a magnetic field generated from the one of the current paths and to convert the detected magnetic field into an electric signal. The first magnetic shield and the second magnetic shield are disposed to face each other with the current path and the magnetic field detection element interposed between the first magnetic shield and the second magnetic shield. The first magnetic shield and the second magnetic shield are configured to shield the magnetic field detection element from an external magnetic field.
