A vehicle lamp includes a reflective member having a silver vapor deposition reflective surface with good durability to prevent cracking or peeling of a protective film and capable of maintaining a high reflectance. The reflective member includes a topcoat layer which serves as a protective film on a silver vapor deposition film which is a silver alloy including Nd on a surface of a base material made of synthetic resin inside a lamp chamber S. The topcoat layerincludes a transparent modified silicone series resin using a silicone resin and an acrylic resin as resin components.

Lamp for vehicle

A reflecting member of a vehicle lamp is provided with a top coat layer formed on a silver deposited coat formed on a surface of a synthetic resin base. The top coat layer is made of a transparent acrylic resin which is synthesized with a monomer whose glass transition temperature is 60&#xb0; C. or higher. The top coat layer adheres to the silver deposited coat to suppress the agglomeration of Ag atoms constituting the silver deposited coat.

Vehicle lamp

A vehicular lamp having an improved luminous intensity of reflected light that has passed through a tinted topcoat layer. Light emitted from a light source bulb is reflected by a reflector to form an outward beam. The reflector is formed of an effective reflector portion contributing to formation of the outward beam and a non-effective reflector portion not contributing to formation of the outward beam. Only the non-effective reflector portion or only the non-effective reflector portion and an extension portion are coated with a tinted topcoat layer. The particle diameter of pigments dispersed in the tinted topcoat layer is limited to a certain range.
