PROBLEM TO BE SOLVED: To provide a continuous manufacturing apparatus of fastener stringers which reliably and accurately performs chamfering on an attachment leg part L of an element continuously manufactured from a metal wire with a Y-shaped cross section without making the device larger-sized and changing a load and a stroke of a fastening hammer. SOLUTION: The continuous manufacturing apparatus has a pair of chamfering punches 113 which are located above the fastening hammer 13, are disposed at a height corresponding to a preceding tooth E' planted on a fastener tape in advance, and chamfer an external edge part of right and left leg parts L' of the preceding tooth E' by moving reciprocally to the side surfaces of the preceding tooth E'.
