PROBLEM TO BE SOLVED: To provide a resin composition for a foamed molding producing a light reflective member excellent in light reflectivity and lightweight properties, a resin sheet for a foamed molding, and a foamed molding. SOLUTION: The resin composition is impregnated with an inert gas, and then heated to give a foamed molding. The resin composition includes 2 or more polyester resins, wherein the difference between the melting point of the polyester resin exhibiting the maximum melting point and the melting point of the polyester resin exhibiting the minimum melting point is≥10°C, or/and the difference between the glass transition temperature of the polyester resin having the maximum glass transition temperature and the glass transition temperature of the polyester resin having the minimum glass transition temperature is≥10°C. The resin sheet for a foamed molding is obtained from the resin composition for a foamed molding. The foamed molding is obtained from the resin sheet for a foamed molding.
