Molded surface fastener and manufacturing method of molded surface fastener

A manufacturing method of a molded surface fastener made of synthetic resin and including a base portion and a plurality of engaging elements standing on the base portion, wherein each of the engaging elements comprises a stem portion standing on the base portion and an engaging portion which is formed integrally with an upper end part of the stem portion and includes a part to extend to an outside of an upper end part outer peripheral edge of the stem portion in a plan view of the engaging element, wherein

• the method including:
• a preliminary step of preparing a composition that lubricant at 0.15 wt % or more and 1.00 wt % or less is added to a thermoplastic resin;
• a primary molding step of melting the composition and molding a primary molded body having the base portion and a plurality of primary elements standing on the base portion;
• and
• a secondary molding step of molding the molded surface fastener in which a top end surface of the engaging element is formed to be flat and the engaging portion has a hanging portion which hangs down obliquely downward toward the base portion by contacting a secondary molding roller with an upper end part of the primary element molded in the primary molding step.
