PROBLEM TO BE SOLVED: To provide a reflector having excellent surface smoothness, which maintains heat resistance and durability under high temperature and high humidity conditions while realizing reduction in the weight of vehicles. SOLUTION: The reflector for a vehicular lighting fixture is formed by using a resin composition prepared by adding an alicyclic structure-containing polymer and a compatibilizing agent to a crystalline olefinic polymer compounded with an inorganic filler and a compatibilizing agent. The resin composition has a specific gravity of 1.2 or less, the weight ratio between the crystalline olefinic polymer and the alicyclic structure-containing polymer of 80/20 to 10/90, the compatibilizing agent in an amount of from 1 to 20% by weight based on the total amount of the crystalline olefinic polymer and the alicyclic structure-containing polymer, the inorganic filler in an amount of from 1 to 23% by weight based on the total amount of the crystalline olefinic polymer and the alicyclic structure-containing polymer.
