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 resistive element (11), a pair of main electrodes (12, 12) separated from the resistive element, and a pair of voltage detection electrodes (13, 13) separated from the main electrodes. The voltage detection electrodes (13) are provided and affixed between the resistive element (11) and the main electrodes (12). The voltage detection terminals (13) are provided with detection terminals (13a) to be connected to terminals of a voltage detection circuit. The resistive element (11) has a columnar shape. Pairs, each of which consists of one voltage detection electrode (13) and one main electrode (12), are secured to both end faces of the resistive element (11) in the longitudinal direction, so that the pairs are opposite to each other. The components are bonded by diffusion boding, friction bonding, wax bonding, etc., after abutting the bonding surfaces with each other.
