PROBLEM TO BE SOLVED: To provide a split mold, which is used for molding a thermoplastic elastomer product and the easy removal of a molded piece from which can be realized by making the proper controlling of the in-mold leftover of the molded piece possible, and its surface treating method.;SOLUTION: This split mold consists of at least two splits and is used for molding the thermoplastic elastomer product. The inner surface of the split, on which a molded thermoplastic elastomer product is to be left-over, is formed so as to have a surface roughness Ra of 0.5-3.0 by blasting treatment. Further, the surface treating method of the split mold, which consists of at least the two splits and is used for molding the thermoplastic elastomer product, is also dealt. The inner surface of the split, on which the molded thermoplastic elastomer product is to be left-over, is blast-treated so as to have a surface roughness Ra of 0.5-3.0.;COPYRIGHT: (C)2007,JPO&INPIT
