Zusammenfassung:PROBLEM TO BE SOLVED: To provide a magnetic balance type current detector being inexpensive to be machined while improving assembly processes. SOLUTION: In the current connector, a bobbin is provided with a pair of terminals to which the ends of conductors forming a coil body are connected, and a plurality of terminals for electrical and mechanical connection to a circuit board. A core made of a ferromagnetic substance forming a closed magnetic circuit including a magnetic gap comprises a pair of approximately U-shaped core pieces butted together to form the closed magnetic circuit including the magnetic gap. The terminals of the bobbin and a magnetic sensitive element are securely connected to respective mounting positions provided on the circuit board, whereby the circuit board and the magnetic sensitive element are fixed on the bobbin. Also, the coil wound on the bobbin is electrically connected by wiring provided on the circuit board, and the plurality of terminals disposed on the bobbin for electrical and mechanical connections are used as input and output terminals.
