A foamed polyester sheet made from a resin composition comprising 50 to 100 wt% of a polyalkylene terephthalate, which resin composition exhibits an isothermal crystallization peak time of 5 to 60 s at a temperature of 100 to150°C, an apparent density (A) of 0.05 to 1.25g/cm<SUP>3</SUP>, and an exothermic crystallization peak temperature (B) of 0 to 150°C as observed in thermal analysis by a power-compensation differential calorimeter. |
