PROBLEM TO BE SOLVED: To prevent the releasability of a molded object from a resin molding mold from deteriorating as a result of the accumulation of deposits on the mold face of the resin molding mold and thereby, maintain the successful releasability. SOLUTION: This resin molding mold is constituted of a top mold 1 and a bottom mold 2; the top mold 1 has a cavity 4 filled with a fluid resin 3 and a resin flow path 5 which is connected with the cavity 4 and allows the passage of the fluid resin 3, and also, has a functional film 7 which functions as a photocatalyst containing a titanium dioxide formed on the mold face 6 configured of a surface including the inner bottom surface of at least the cavity 4 out of the surfaces of the top mold 1. As the functional film 7 irradiated with an ultraviolet light 8 functions as a photocatalyst, a strong oxidation decomposition force is generated on/near the surface of the functional film 7. Consequently, the releasability of the deposit on the surface of the functional film 7, that is, the molded object from the top mold 1, is ameliorated because the top surface of the molded object is decomposed. Further, the retention of the successful releasability due to the irradiation of the functional film 7 with the ultraviolet light 8, is ensured. Also, the method for manufacturing the resin molding tool and the resin molding method are provided. COPYRIGHT: (C)2006,JPO&NCIPI
