Abstract: A current sensor includes a plurality of individual sensors and a wiring case. Each of the individual sensors includes an electrical-conduction member through which a measurement current to be measured flows, a magnetoelectric converter and an insulating sensor housing. The magnetoelectric converter converts a measurement magnetic field caused by a flow of the measurement current into an electric signal. The sensor housing accommodates the electrical-conduction member and the magnetoelectric converter therein. The wiring case is larger than the sensor housing. The wiring case includes 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 megnetoelectric converter of each of the plurality of individual sensors.

Abstract: A current sensor includes a wiring board, a shield, an insulating sensor housing, and a shield adhesive. The wiring board and the shield are accommodated in the sensor housing. The sensor housing has a shield support part to support the shield, and a shield adhesion part. An application surface of the shield adhesion part is further from the shield than a contact surface of the shield support part. The shield is mounted on the contact surface of the shield support part, and the shield adhesive is disposed between the application surface of the shield adhesion part and the shield. The shield and the wiring board are aligned with and spaced from each other in the sensor housing.

Abstract: A current sensor includes an electrical-conduction member, a magnetoelectric converter and a shield. The shield includes a first shield and a second shield 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 located between the first shield and the second shield extends in an extension direction along the surface of the second shield. The second shield has two sides aligned in a lateral direction perpendicular to the extension direction, and has a plurality of extending parts extending toward the first shield at the sides and being aligned with and separated from each other in the extension direction. The magnetocelectric converter is located between the plurality of extending parts.

Abstract: A current sensor includes an electrical-conduction member, a magnetoelectric converter and a shield. The shield includes a first shield and a second shield 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 first shield and the second shield. The part of the electrical-conduction member located between the first and second shields extends in an extension direction that is along the surface of the first shield. In at least one of the first shield and the second shield, a center part has a length greater than lengths of opposite end parts in a lateral direction that is along the surface of the first shield and perpendicular to the extension direction. The magnetoelectric converter is located between the opposite end parts of the first and second shields in the extension direction.
