Abstract
Provided is a shunt resistor which has an excellent accuracy of current detection and a small temperature drift as well as a compact structure, and improves the operability. The shunt resistor is provided with a resistance body (), a pair of main electrodes () separated from the resistance body, and a pair of voltage detection electrodes () separated from the main electrodes. The voltage detection electrodes () are provided and fixed between the resistance body () and the main electrodes (). The voltage detection electrode () is provided with a detection terminal () to be connected to a terminal of a voltage detection circuit. The resistance body () has a columnar shape. The voltage detection electrode () and main electrode () are fixed to both end faces of the resistance body () in the length direction, so that they are opposing each other. The components are bonded by diffusion boding, friction bonding, wax bonding, etc., after abutting the bonding surfaces with each other.
