Abstract
A high-accuracy current detecting resistor is provided whose resistance does not change greatly according to temperature change and which has an excellent dielectric strength. In a resistor in which an electrical resistance alloy plate and a radiating metallic plate are laminated via a resin insulating layer, the electrical resistance alloy plate is formed of an alloy containing nickel and copper and is adhered to the resin insulating layer by etching a grain boundary of the alloy in the form of a concave.
