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.degree. 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.
