<p>Provided is a current detecting resistor, which has a compact size and excellent heat dissipating characteristics and can perform highly accurate and stable operation. The resistor is provided with: a resistor body (12a) composed of a metal foil; a pair of electrodes (11a) bonded on one surface of the resistor body; a base plate (14a), which is bonded on the other surface of the resistor body with an insulating layer (13) therebetween, covers a region between the pair of electrodes in the resistor body and also at least a part of a region where the electrodes are arranged; a first protection film (15) which covers the resistor body in the region between the pair of electrodes; and a second protection film (16) which covers the base plate. Furthermore, the resistor body (12a) in the region between the electrodes is provided with a slit (S) in the width direction, and a small-width meandering current path is formed by the slit, at the vicinity of the both electrodes (11a), with a large width at the center portion between the elctrodes.</p> |
