To provide a shunt resistor and a current detection device including the shunt resistor, to which a busbar, a board, and the like can be easily fixed with sufficient strength wherein only minimum processing of electrodes is required. Screwing members (bolt (14) and nut (15)) that are separate members from electrodes (12) of the resistor (10), are fixed on the electrodes (12). The current detection device includes the shunt resistor (10), which has at least a pair of electrodes (12). One screwing member (14) fixed beforehand on at least one electrode (12) is screw fastened with the other screwing member (15) while disposing a prescribed intervening member (20) between the one screwing member and the other screwing member. Here, the prescribed intervening member (20) includes a board mounting a current detection circuit thereon and/or busbars.
