In manufacturing a continuous surface fastener tape (1) on an injection molding machine (11), a male engaging portion (3) is injection molded on one surface of a continuous substrate sheet (5) of thermoplastic resin at one longitudinal margin, and an adhesive agent is applied to the other surface of the substrate sheet (5) at the other longitudinal margin to form an adhesive layer (6). The surface fastener tape (1) is stored in superposed form, such as in roll or in stack, and can be cut into individual surface fastener pieces (2) for use as it is demanded. In production, molten resin is continuously injected to the die wheel (12) from an injection nozzle (16) to mold the continuous surface fastener tape (1), and the adhesive layer (6) is formed on the surface fastener tape (1) using an adhesive-agent applicator (19).
