A method for manufacturing a molded surface fastener may include using, as a synthetic resin forming the molded surface fastener, a thermoplastic resin having a melt flow rate of 20 g/10 min or more and 60 g/10 min or less and a flexural modulus of 1000 MPa or more and 2300 MPa or less. Consequently, an engaging element in which a top end surface of an engaging head portion is flat, and at least a part of a back-side proximal end surface of the engaging head portion has an angle of 70&#xb0; or more and 110&#xb0; or less with respect to a height direction of the stem portion can be stably molded, and thus the molded surface fastener that has a high peel strength and a good texture can be obtained.

Method for manufacturing molded surface fastener and molded surface fastener

Provided is a molded surface fastener capable of stably having high engaging strength with respect to a loop member. The molded surface fastener of the present invention includes a base portion and a plurality of engaging elements provided with a stem portion and an engaging portion, and is formed of synthetic resin containing lubricant at 0.15 wt % or more and 1.00 wt % or less. 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.
