PROBLEM TO BE SOLVED: To provide a luminaire housing having a reflecting film consisting of a silver plating layer adhered to the base body part of the housing through a primer layer, and a method for producing it. SOLUTION: This luminaire housing is obtained by forming, particularly, on the inner surface of a luminaire housing, a primer layer consisting of (1) alkoxysilane, (2) colloidal silica and at least one of silane coupling agent and titanium coupling agent, (3) a metal oxide colloide and at least one of silane coupling agent and titanium coupling agent, or (4) metal alkoxide, and a resin, forming a masking layer consisting of a water-soluble polymer on the surface of the primer layer of a light transmissive part, forming a reflecting film consisting of a silver plating layer thereon, and dipping the resulting housing in hot water, and dissolving the masking layer to remove the silver plating layer of the light transmissive part. Further, a transparent protecting layer for protecting the silver plating layer can be also provided on the surface of the silver plating layer.
