PROBLEM TO BE SOLVED: To provide a polyester foam sheet having excellent surface appearance, lightweight property, shape formability, and optical reflectivity, and to provide a method for producing the same. SOLUTION: This polyester resin composition foam sheet which comprises a polyester resin composition comprising (A) 80 to 99.5 wt.% of a crystalline polyester resin and (B) 0.5 to 20 wt.% of a foaming nucleating agent is characterized in that the MFR (melt flow rate) [a measured value under conditions at (the melting point of the foam sheet +25°C) and a load of 2.16 kg] of the polyester foam sheet is≤15 (g/10 min).
