Beschreibung
Zusammenfassung:	The present invention aims to provide a thermoplastic polyester elastomer resin composition suitable for foam molded product which exhibits light weight, excellent rebound resilience and excellent surface smoothness. The present invention provides a thermoplastic polyester elastomer resin composition for counter-pressure foam molding, containing a thermoplastic polyester elastomer and a thickener, wherein the thermoplastic polyester elastomer is prepared by bonding a hard segment and a soft segment, wherein the hard segment consists of polyester constituted from aromatic dicarboxylic acid and aliphatic and/or alicyclic diol as constituting components, wherein the soft segment is at least one member selected from a group consisting of aliphatic polyether, aliphatic polyester and aliphatic polycarbonate, wherein the thermoplastic polyester elastomer has a soft segment content of 25 to 90% by mass, and wherein a content of the thickener is 0.05 to 4.5 parts by mass relative to 100 parts by mass of the thermoplastic polyester elastomer. The present invention also provides a foam molded product that includes a continuous phase formed of the thermoplastic polyester elastomer resin composition.
