摘要：
There is provided a polymer film including a polymer; and a high molecular weight plasticizer that has a number average molecular weight of 700 to 10,000 and has a repeating unit derived from a dicarboxylic acid and a diol, wherein the dicarboxylic acid for forming the high molecular weight plasticizer includes at least one aliphatic dicarboxylic acid having 2 to 20 carbon atoms and at least one aromatic dicarboxylic acid having 8 to 20 carbon atoms, and the diol includes at least one diol selected from the group consisting of an aliphatic diol having 2 to 12 carbon atoms, an alkyl ether diol having 4 to 20 carbon atoms and an aromatic ring-containing diol having 6 to 20 carbon atoms.
