Abstract

Provided is a polyhydroxyalkanoate resin composition containing a polyhydroxyalkanoate resin component. In differential scanning calorimetry of the resin composition, a highest melting peak temperature is 130° C. or higher, and a total crystalline melting enthalpy calculated from all melting peaks is in the range of 20 to 65 J/g. Preferably, the polyhydroxyalkanoate resin component is a mixture of at least two polyhydroxyalkanoate resins differing in crystalline melting enthalpy.
