Abstract: Provided is a current detection device in which, to a bus bar type shunt resistor, another member can be easily connected and fixed by means of rotational fastening of screw members. The current detection device is provided with: a pair of wiring members (11, 12) consisting of electrically conductive metal material; a resistor body (13) consisting of metal material having a smaller temperature coefficient of resistance than the wiring members and which is bonded to the wiring members; and a screw member (16) which is fixed to at least one of the wiring members and which is a separate member from the wiring members. One screw member (16) is fixed to one surface of the wiring members (11, 12), and another screw member (17) is rotationally fastened to the one screw member (16) sandwiching another member (18, 19) disposed on the other surface of the wiring members (11,12).
