PURPOSE: Provided are a novel polyhydroxyalkanoate and a manufacturing method by a microorganism capable of substantially reducing unintended monomer units and obtaining the polyhydroxyalkanoate in a high yield. CONSTITUTION: The polyhydroxyalkanoate has a composition of monomer units represented by the following formula(1):AxB(1-x) wherein A is at least one or more represented by the following chemical formula(2)(wherein, n is any integer of 1 to 8; and R is any one selected from the group consisting of a halogen atom, -CN, -NO2, -CH3, -C2H5, -C3H7, -CF3, -C2F5 and -C3F7); B is at least one or more selected from monomer units represented by the following chemical formula(3) or (4)(wherein, p is any integer of 0 to 10, and q is an integer of either 3 or 5); and x is 0.01 or more and not exceed 1. A microorganism capable of synthesizing a novel polyhydroxyalkanoate having 3-hydroxy-substituted benzoylalkanoic acid as a monomer unit using a substituted benzoylalkanoic acid as a material is cultured in the medium containing a substituted benzoylalkanoic acid, then the polyhydroxyalkanoate produced in the cultured bacteria is extracted and recovered.
