ABSTRACT:
A lens molding die for producing a lens, which comprises a base member made of a hard material and having one surface of a predetermined shape; and a resin-molded layer formed on the one surface of the base member and having a surface shape corresponding to a predetemined shape of a lens to be molded. The resin-molded surface is to be made of a resin material which is inactive with a material which is to be molded by the lens molding die. The resin-molded layer is formed by introducing the material into the space formed between the one surface of the base member and a transfer surface formed on a transfer die correspondingly to the surface of a lens to be produced to be cured by heat or ultraviolet rays.
