A method of making specified-length wires for wire harness from continuous wires consists of the steps of: fixing a front end of the U-bent continuous wire and pulling the U-bent wire to pay out a predetermined amount thereof; and cutting the U-bent, pulled wire at a portion almost opposite to the fixed front end. An apparatus for putting the above method into practice comprises: a rotatable wire bending head for holding the front end of a continuous wire by wire clamp plates and bending the wire in a U-shape; a wire pulling head for engaging or holding the U-shaped portion and pulling it in the axial direction of the wire to pay out a predetermined amount thereof; and a cutting blade for cutting the U-bent, pulled wire at a position almost opposite to the front end.
