Abstract: 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.

Abstract: Provided is a current detection resistor that is small and that inhibits influence of the skin effect due to high frequency current. The resistor includes a resistor body (11) and at least a pair of electrodes (12), wherein the resistor body (11) is configured in a pillar-shape having diameter of 4 mm or less disposed between the electrodes. Each of the electrodes (12) is made to be longer in the direction in which the electrodes are placed and longer than twice the distance between the electrodes, which sandwich the resistor body. Further, each of electrodes (12) is square pillar-shaped, and the resistor body is fixed to roughly to center of the electrode in cross-section.
