A surface fastener molded of synthetic resin, comprises: a plate-like substrate (1); and a multiplicity of hooks (2) formed on one surface of the substrate (1) integrally, each of the hooks (2) being composed of a rising portion (21) having a front surface (24) rising from the substrate (1), a rear surface (23) rising obliquely from the substrate (1) along a smooth curved line and a reinforcing rib (2a) located on at least one side surface, and a hook-shape engaging portion (22) extending forwardly from a distal end of the rising portion (21). After the molding, the plate-like substrate (1) is biaxially stretched to have a smaller thickness and, at the same time, to increase the toughness in substantially all directions of the substrate (1). <IMAGE> |
