PROBLEM TO BE SOLVED: To provide a method for producing a cast and cured product having heat resistance, a large elongation and high toughness. SOLUTION: This method for producing the cast and cured product comprises casting a photocurable resin composition comprising (A) 100 pts.wt. unsaturated polyester resin and/or vinyl ester resin, (B) 0-300 pts.wt. filler in a powder shape, and (C) 0.1-10 pts.wt. photopolymerization initiator composed of a cation of a coloring matter having photosensitivity within a visual light region or a near infrared region, for example, represented by the general formula (1) D+.A- (D+ is the cation of the coloring matter having photosensitivity within the visible light region or the near infrared region; and A- is a various kind of anion), and an organic boron compound represented by general formula (2) (Z+ is an arbitrary cation; and R1, R2, R3 and R4 are each independently an alkyl group or the like), and irradiating the resultant photocurable resin composition with the light to cure the composition.
