1. A current sensor comprising:
a plurality of individual sensors, each including:
an electrical-conduction member through which a measurement current to be measured flows;
a magnetoelectric converter that converts a measurement magnetic field caused by a flow of the measurement current into an electric signal; and
an insulating sensor housing that accommodates the electrical-conduction member and the magnetoelectric converter therein; and
a wiring case being larger than the sensor housing, and including:
an insulating integrated housing in which the plurality of individual sensors is fixed; and
an input/output wiring disposed in the integrated housing and electrically connected to the magnetoelectric converter of each of the plurality of individual sensors, wherein
the insulating sensor housings of the plurality of individual sensors are provided individually from each other and are separate members from the insulating integrated housing, and
the electrical-conduction member of each individual sensor is directly fixed to the insulating sensor housing.
