Abstract
A molded male surface fastener includes resin invasion preventing walls, 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 made of a thermoplastic resin, a plurality of engaging elements provided between left and right resin invasion preventing walls, and a linear sealing body that is continuously disposed in the longitudinal direction of the base member along a peripheral portion of a top portion of each resin invasion preventing wall. When an engaging element forming surface of the surface fastener is placed on a concavo-convex surface of foaming body molding cavities of a foaming mold, if the mold has the same magnetic force as that in the related art, the linear sealing body is well adhered along the concavo-convex surface.
