<p>Provided is a polyester resin foam that has a fine and uniform air bubble structure, that does not have wrinkles or the like on the surface thereof, that has a satisfactory outer appearance, that exhibits excellent workability, and that has good flexibility. The polyester resin foam is formed by foaming a polyester resin composition containing a polyester resin that has an endothermic peak top temperature of 200 °C or less and a storage elastic modulus of 10 MPa or lower at a temperature that is 5 °C lower than the endothermic peak top temperature, and is characterized by having an apparent density of 0.030-0.150 g/cm3.</p> |
