Abstract: Provided are PHA particles which are excellent in dispersibility in an aqueous dispersion and have excellent film formation capability, in which odor of a molded body obtained from the PHA particles or an aqueous dispersion of the PHA particles is suppressed, and whose color tone is good, and an aqueous dispersion of the PHA particles. Polyhydroxyalkanoate particles including polyhydroxyalkanoate having a particle shape and peptidoglycan covering a portion of or an entire surface of the polyhydroxyalkanoate. In this polyhydroxyalkanoate particle, a content of polyhydroxyalkanoate is 98.0% by weight or more, and a content of peptidoglycan is 0.1% by weight or more and 1.0% by weight or less.
