Abstract: A plasticizer for a vinyl chloride resin with excellent balance of non-transfer properties, fogging resistance, flexibility, heat resistance, and cold resistance is provided. Specifically, a plasticizer for a vinyl chloride resin is a polyester made from a glycol having 2 to 18 carbon atoms, an aliphatic dicarboxylic acid having 4 to 14 carbon atoms, and a monoalcohol having 4 to 18 carbon atoms and/or a monocarboxylic acid having 2 to 21 carbon atoms, as reaction raw materials, in which the polyester has a number average molecular weight in a range of 500 to 6,000 and contains components with a molecular weight of 600 or less in a range of 0.5 to 3.0% by mass in terms of area ratio in gel permeation chromatography measurement.
