This poly(lactic acid) derivative is represented by general formula (1) or general formula (2). In general formula (1), one of X1 to X5 is an aldehyde group, one of the remaining four is an alkoxy group, and the remaining three are hydrogen atoms. Provided is the poly(lactic acid) derivative represented by general formula (2). In general formula (2), one of R1 to R3 is a chlorine atom, a fluorine atom, an aldehyde group, an alkoxy group, an alkyl group or an ester, and each of the remaining two is a chlorine atom, a fluorine atom, an aldehyde group, an alkoxy group, an alkyl group, an ester or a hydrogen atom. |
