A method of molding a composite insulator having a core member and an overcoat portion arranged on an outer surface of the core member, in which a core member having metal fittings at both ends thereof is set in a metal mold for molding the composite insulator, overcoat portion forming materials are filled in a cavity for molding said overcoat portion formed around the core member, and then the overcoat portion forming materials are cured by heat, is disclosed. The improved method includes a step of making a temperature increase of the overcoat portion forming materials near the metal fittings equal to that of the other portion, when the overcoat portion forming materials are cured by heat, by utilizing an additional heating means.
