ABSTRACT:
A resin mold for molding a curable resin, which has been made by molding a resin composition comprising an alicyclic structure-containing polymer and a nitrogen-containing organic compound (X) having at least one nitrogen atom which is bonded to at least one tertiary or quaternary carbon atom. A curable resin is molded and cured using a combined mold which is a combination of two resin molds (A) and (B), wherein at least one (A) of the two resin molds is made by molding a resin composition comprising an alicyclic structure-containing polymer and the nitrogen-containing organic compound (X). Preferably, the two molds (A) and (B) are made by molding resin compositions comprising an alicyclic structure-containing polymer and different amounts of the nitrogen-containing organic compound (X).
