Beschreibung
Zusammenfassung:	[Abstract] A modified polyester resin production method, including a step of allowing a polyhydroxyalkanoic acid to react with a reactive raw material satisfying at least any one of Condition (A-1) and Condition (A-2) described below, and Condition (B) described below, in the absence of a solvent and at a reaction temperature lower than a decomposition temperature of the polyhydroxyalkanoic acid.Condition (A-1): The reactive raw material contains a diol and a dicarboxylic acid component.Condition (A-2): The reactive raw material contains a polyester resin other than the polyhydroxyalkanoic acid.Condition (B): A ratio of an aromatic monomer configuring the reactive raw material in the reactive raw material is 0% by mole or more and less than 50% by mole.
