PROBLEM TO BE SOLVED: To provide a metal wire supply device capable of simply manufacturing wire netting having small fluctuation of tensile force acting on a metal wire and having small unevenness in quality when releasing the metal wire wound around a bobbin. SOLUTION: This metal wire supply device supplies the metal wire 5 by releasing it from a metal wire wound body 6 wound around the bobbin 2 with a flange mounted around a bobbin shaft 3 turnably while turning the bobbin. A detection roller 13 provided at an end of a detection part arm 11 swinging freely is abutted on a surface of the metal wire wound body 6, and a braking part shoe 10 provided at an end of a braking part arm 8 swinging freely is brought into pressure-contact with the flange 1 of the bobbin. Both ends of an extension spring 17 are engaged with the detection part arm 11 and the braking part arm 8 to reduce fluctuation of tensile force acting on the metal wire when releasing the metal wire by bringing pressing force reduced in accordance with reduction of diameter of the metal wire wound body 6 reduced in accordance with release of the metal wire 5 into pressure-contact with the flange of the bobbin.
