[PROBLEMS] To provide a molding method for molding a molded product having excellent heat resistance from a thermoplastic resin having a high ratio of raw materials derived from biomass resources, with the same moldability as that of a conventional petroleum resin. A thermoplastic resin (A) composed of a microorganism-produced polyhydroxyalkanoate containing structural units represented by the following chemical formula (1) and chemical formula (2), and a thermoplastic resin (B) composed of polylactic acid. a method of molding a resin composition containing, - [- O-CH ( CH 3) -CH 2 -CO -] - ··· (1), - [- O-CH (R) -CH 2 - CO −] − (2) [wherein R is C n H 2n + 1 (n = 2 to 14). When the molar fraction of the structural unit represented by the chemical formula (1) with respect to the thermoplastic resin (A) is c, and the mold temperature in the molding of the resin composition is T ° C., the following (3) and ( 4), 122.9c 2 −30.4 ≦ T (3), 25 ≦ T ≦ 90 (4) [Selection figure] None |
