Abstract: Provided is a compact and easily mountable current detection device in which a resistor body can be easily inserted in a current path, and a voltage value produced by the current can be easily obtained. The current detection device comprises a unit metal member (11A, 11B, 11C) that pass a current to be detected, a pair of voltage terminals (14, 14), which obtain a voltage signal from the unit metal member, and a holding member (16) that holds a plural of the unit metal members in parallel. A plural of the unit metal members (11A, 11B, 11C) is interposed between the holding member (16) and the board (17) on which a plural of wiring patterns is formed, and each pair of the voltage terminals (14, 14) of the unit metal member is connected to each wiring pattern formed on the board.
