Abstract

PURPOSE: To obtain a molded product with high preciseness within a short time by putting a molded article in a highly precise mold along with a liquid resin which is quickly cured by radioactive rays or ultraviolet rays to be irradiated by radioactive rays or the like.
CONSTITUTION: A molded article 1 is fabricated from a transparent plastic material and, on the other hand, a highly precise mold 5 of which the inner surface shape and the dimension are formed in a extremely high preciseness and which is made of a material transparent to radioactive rays or ultraviolet rays is provided. The molded article 1 is putted in this high precise mold 5, along with a radiation or an ultraviolet ray curable type transparent resin 6. In this condition, when radioactive rays or ultraviolet rays are irradiated from a lower part, the liquid resin 6 is rapidly cured to form the highly precise molded product 7 integrated with the molded article 1.
