PURPOSE: Polyhydroxyalkanoates(PHA) and a method of producing the same by utilizing microorganisms are provided, thereby producing PHA containing monomer units of various structures having substituents useful for device materials, medical materials, etc. in the side chains, and producing the PHA with little contamination of monomer units and in a high yield. CONSTITUTION: The polyhydroxyalkanoate comprises one or more of monomer units represented by Formula (1), wherein R is at least one selected from the group represented by any one of Formulas (2), (3) and (4); in Formula (2), R1 is selected from the group consisting of hydrogen atom (H), halogen atom, -CN, -NO2, -CF3, -C2F5 and -C3F7, and q is an integer of 1 to 8; in Formula (3), R2 is selected from the group consisting of hydrogen atom (H), halogen atom, -CN, -NO2, -CF3, -C2F5 and -C3F7, and r is an integer of 1 to 8; in Formula (4), R3 is selected from the group consisting of hydrogen atom (H), halogen atom, -CN, -NO2, -CF3, -C2F5 and -C3F7, and s is an integer of 1 to 8; provided that following R is not selected: when one kind of R is selected: R being R1=H and q=2, or R1=H and q=3 in Formula (2), R being R2=halogen and r=2, R2=-CN and r=3, R2=-NO2 and r=3, or R2=H and r=1 or 2 in Formula (3), or R being R3=H and s=1, 2 or 3 in Formula (4); when two kinds of R are selected: a combination of R being R1=H and q=3 and 5 respectively in Formula (2), a combination of R being R2=H and r=2 and 4 respectively, a combination of R being R2=H and r=2 and 6 respectively, and a combination of R being R2=halogen and r=2 and 4 respectively in Formula (3); when three kinds of R are selected: a combination of R being R1=H and q=3, 5 and 7 respectively in Formula (2), a combination of R being R2=H and r=1, 3 and 5 respectively, and a combination of R being R2=H and r=2, 4 and 6 respectively in Formula (3).
