Abstract: A thermoplastic polyester resin foam sheet including: a thermoplastic polyester resin; and at least one crystallization accelerator selected from an inorganic crystallization accelerator and an organic crystallization accelerator, wherein the thermoplastic polyester resin foam sheet has a crystallization time of 14 minutes or less, determined from a DSC curve obtained using a heat flux differential scanning calorimetry (DSC) apparatus by performing a second heating from 30° C. to 110° C. at a heating rate of 100° C./min, and holding the temperature at 110° C. for 30 minutes, wherein the crystallization time is determined in terms of a time between initiation of the second heating and a time of emergence of a peak top of a last appearing exothermic peak in the DSC curve.
