A nonslip member in which a large number of nonslip convexes are fixed to an upper surface of a base fabric performing an anchoring action, and the nonslip convexes are made of rubber. By engaging a male mold and a female mold with each other, a large number of small pieces coincident to a shape of through holes of the female mold are punched out from a plate-like material. By pressurizing and heating each small piece between a punching convex and a mounting base while engaging the male mold and the female mold with each other, the small piece is bridged and fixed to the base fabric to serve as a nonslip convex.
