Abstract: Provided is a method for producing a resistor, including a step of forming a through-hole in a sheet-like conductive material; a step of fitting a resistive element piece into the through-hole and thus forming joint portions where end surfaces of the resistive element piece are joined to respective side surfaces of the conductive material exposed by the through-hole; and stamping a region including the joint portions from the conductive material, thereby forming a resistor including a resistive element and a pair of electrodes.

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: 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.
