Beschreibung
Zusammenfassung:	According to the present invention, there is provided a foam molded product of thermoplastic polyester elastomer resin which exhibits light weight and excellent rebound resilience. The foam molded product is characterized in that, the foam molded product has a foamed layer consisting of a resin phase and an isolated foamed cell, wherein the resin phase contains a thermoplastic polyester elastomer (A), wherein the thermoplastic polyester elastomer (A) is prepared by bonding a hard segment and at least one soft segment, wherein the hard segment consists of polyester constituted from aromatic dicarboxylic acid and aliphatic and/or alicyclic diol as constituting ingredients, wherein the at least one soft segment is selected from a group consisting of aliphatic polyether, aliphatic polyester and aliphatic polycarbonate, wherein a content of the soft segment is 55 to 90% by mass, wherein an average cell diameter of the foamed cell is 10 to 400 µm, wherein the maximum cell diameter of the foamed cell is 10 to 500 µm, wherein rebound resilience of the foam molded product is 60 to 90%, and wherein density of the foam molded product is 0.1 to 0.35 g/cm3.
