Abstract
A resin part of a vehicular lamp and a method for producing such a part in which a metallic vapor deposition coating for forming a reflective surface is formed directly on a surface of a resin body part without applying an undercoating layer. The body of the resin part is produced by injecting molten resin into a cavity of a molding die in which a heat insulating layer is formed on a portion of the cavity surface corresponding to the reflective surface. A metallic vapor deposition coating is applied directly to the portions of the body of the resin part which were in contact with the heat insulating layer during injection molding.
