PROBLEM TO BE SOLVED: To obtain a plasticizer for resins excellent in plasticity, transparency retention of the resins to which the plasticizer is applied, and transition resistance of the plasticizer in the resins, and having a low viscosity and excellent also in workability. SOLUTION: This plasticizer for vinyl and polycondensed resins comprises an ester of an aromatic polycarboxylic acid or its ester-forming derivative and a specific (poly)oxyalkylene monohydrocarbyl ether, and it has an SP value (SPk) of 9-12, and the absolute value of the difference of SPk and the SP value of the resin (SPj),|SPk-SPj|, is not greater than 2.5.
