Abstract: [MEANS FOR SOLVING PROBLEMS] A thermally-meltable resin layer (3) which does not melt or hardly melts at a given heating temperature is formed on one side of a base cloth (1). Subsequently, a silicone resin in a molten state is molded on the other side to thereby form antislipping surfaces (2, 2) composed of flat planes of a small width. Thereafter, a thermally-meltable resin layer (4) which melts at the given temperature is formed on the outer side of the thermally-meltable resin layer (3). [EFFECTS] This slip prevention member is fitted to a strip (5) to be attached to the back side of the waist of pants or a skirt. The resultant waistcloth (A) is attached to the back side of the waist of pants or a skirt. Due to the antislipping surfaces (2, 2) arranged in rows, the slip prevention member can retain an extremely satisfactory antislipping effect for long as compared with a slip prevention member having small projecting surfaces arranged scatteringly.
