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