Abstract: A plastic molding, such as a key top with signals or letters appearing on its face, has a first part molding having projections formed at its top defined an enclosed area. A second part molding of a color other than that of the first part molding is adhered to the surface of the first part molding in a manner permitting the ends of the projections to be exposed. The first part molding has a plurality of through holes formed in mesh configuration. At least one of the projections corresponds to at least one of the through holes. The second part molding is adhered to the first part molding to be buried in the plastic material of the second part molding. Part of the plastic material of the first part molding is filled into the enclosed area via the through holes. In a method of making such plastic molding, an inner member of the mold die may be used commonly regardless of the sign or letter provided in the plastic molding.
