A molded male surface fastener (1) comprises resin invasion preventing walls (4), which prevent an invasion of a molding foamable resin material of a cushion body, on right and left edge portions along a longitudinal direction of a surface of a flat base member (2) made of a thermoplastic resin, a plurality of engaging elements (3) provided between left and right resin invasion preventing walls (4), and a linear sealing body (5) that is continuously disposed in the longitudinal direction of the base member (2) along a peripheral portion of a top portion of each resin invasion preventing wall (4). When an engaging element forming surface of the surface fastener (1) is placed on a concavo-convex surface of foaming body molding cavities of a foaming mold (100), if the mold has the same magnetic force as that in the related art, the linear sealing body (5) is well adhered along the concavo-convex surface. Therefore, sealing performance between the mold and the resin invasion preventing walls (4) can be greatly improved. As a result, even when foam molding is performed, a foamable resin material (200) is not invaded into an engaging element forming region, and the molded male surface fastener (1) can be accurately molded and integrated at a predetermined position of a foaming body. |
