Abstract
To provide a surface fastener capable of stably ensuring an appropriate peel strength with respect to a loop member and capable of improving texture as compared with a conventional surface fastener. A surface fastener is made of a synthetic resin and includes: a base portion; and a plurality of engaging elements. Each of the engaging elements includes a stem portion, an engaging head portion, and at least one engaging portion protruding from an outer circumference portion of the engaging head portion. A total of the areas of the engaging head portions per 1 cmof the surface fastener is 10,000,000 μmor more when the surface fastener is viewed in plan view from above. The synthetic resin has a tensile modulus of 700 MPa or more and 2300 MPa or less.
