A surface fastener includes a base portion and a plurality of engaging elements, the base portion and the engaging elements include a thermoplastic resin at least partially including a plant-derived resin, the plant-derived resin has an MFR of 5 g/10 min or more and 30 g/10 min or less, and has a flexural modulus of 800 MPa or more and 2300 MPa or less, and, in plan view of each of the engaging elements, the engaging head portion is such that at least a part of the engaging head portion has a shape protruding outward with respect to an upper end of the stem portion. Therefore, the surface fastener can include a plurality of engaging elements. In addition, compared to the related art, it is possible to reduce the use of fossil-resource-derived resin to thereby reduce the load on the environment.
A surface fastener comprising a base portion and a plurality of engaging elements that are provided on one surface of the base portion, each engaging element including a stem portion that extends upward from the base portion and an engaging head portion that is integrally formed with an upper end of the stem portion, wherein
