PROBLEM TO BE SOLVED: To provide an expanded sheet of a thermoplastic polyester resin which has a presentable appearance with fine surface air bubbles, can make a highly precise molded object despite the fact that it uses a recovered thermoplastic polyester resin as a raw material and is highly compatible with environments, and a molded object of this sheet and its manufacturing method. SOLUTION: In this expanded sheet of the recovered thermoplastic polyester resin containing not lower than 60 wt% recovered thermoplastic polyester resin, the surface average air bubble diameter is 0.2 to 0.5 mm, the inner average air bubble diameter is 0.2 to 0.5 mm, the density is 0.1 to 0.7g/cm<SP>3</SP>and the thickness is 0.3 to 3.3 mm.
