Abstract: Provided is a resistor including a first electrode, a second electrode, and a resistive element disposed between the first and second electrodes. Each of the first and second electrodes includes a main electrode portion and a narrow electrode portion with a narrower width than that of the main electrode portion. The resistive element is disposed between the two narrow electrode portions.

Abstract: Provided is a current sensing device including an electrical conductor made of electrically conductive metal; and voltage sensing terminals provided on the electrical conductor. Each voltage sensing terminal is formed by inserting bar-like metal into a through-hole formed in the electrical conductor, and the voltage sensing terminal includes a first terminal portion that is stored in the through-hole and a second terminal portion that protrudes from the through-hole.

Abstract: In a metal plate resistor, the bonded surface between the resistance body and the electrode can be prevented from peeling off. The metal plate resistor comprises a resistance body; an electrode consisting of metal material having a higher conductivity than the resistance body, and the electrode bonded with the resistance body; a recessed portion formed in an end face of the electrode on a side bonded with the resistance body; and a fixation hole formed in the electrode for inserting a bolt; wherein an end portion of the resistance body is fitted into the recessed portion in the electrode. The recessed portion is provided with wall portions on both sides in a width direction of the resistance body, and in a direction substantially perpendicular to a penetration direction of the fixation hole. The recessed portion is opened to an end face and a first surface of the electrode.
