In a molded surface fastener manufacturing method, molten resin is injected or extruded from an injection die or an extrusion nozzle, and at the same time, a coarse mesh core sheet is introduced between the extruded molten resin and the circumferential surface of a die wheel, which has a multiplicity of hook-element-forming circumferential cavities. The core sheet is forced against the circumferential surface of the die wheel by a pressing force of a press roller or under a molten resin pressure at the time of injection to pass part of the molten resin through pores of the core sheet and to fill in the hook-element-forming cavities. As a result, a multiplicity of hook elements are molded, and at the same time, the core sheet is embedded integrally in a plate-shaped substrate sheet closer to the hook-element-surface side.
