Zusammenfassung:	It is an object of the present invention to provide a polyhydroxyalkanoate P(3HB-co-3HHx) comprising 3-hydroxybutanoate and 3-hydroxyhexanoate, the polyhydroxyalkanoate having high melt fluidity and excellent processability.In order to solve the problems described above, the inventors of the present invention found that with regard to a polyhydroxyalkanoate comprising 3-hydroxybutanoate and 3-hydroxyhexanoate, when the polyhydroxyalkanoate is produced by using microorganisms, and thereby the content of 3-hydroxyhexanoate is increased, a polyhydroxyalkanoate having novel physical properties is obtained. That is, the present invention provides the following polyhydroxyalkanoate, a molded body thereof, and a method for producing the polyhydroxyalkanoate. The polyhydroxyalkanoate of the present invention is a polyhydroxyalkanoate comprising a 3-hydroxybutanoate unit and a 3-hydroxyhexanoate unit, the polyhydroxyalkanoate having a melt flow rate at 160°C and 2.16 kg/f of 2.5 g/10 minutes or more.
