摘要：
A process of producing a thermoplastic polyester series resin foamed material is disclosed, which comprises heating and further foaming a thermoplastic polyester resin foamed material having a crystallinity of not higher than 30% by bringing into contact with water or steam of at least 60°C and then heating the foamed material by bringing into contact with a heating medium other than water of at least 100°C to further foaming the foamed material. A process of producing a thermoplastic polyester series resin foamed material is also disclosed, which comprises heating and further foaming a thermoplastic polyester series resin foamed material having a crystallinity of not higher than 30% by bringing into contact with water to steam of at least 60°C, heating and further foaming the foamed material by bringing into contact with a heating medium other than water of at least 100°C, and molding the foamed material by a mold.
