Summary:PROBLEM TO BE SOLVED: To provide a polyester film originated from a biomass resource which can substantially contribute solution of environmental problems, depletion problems of fossil fuel resources and so on and has practical properties.SOLUTION: A polyester film originated from a biomass resource is obtained from a polyester composed of repeating units comprising dicarboxylic acid and diol units, and at least one of dicarboxylic acid and diol raw materials for the polyester is originated from a biomass resource. The content of terminal carboxyl groups in the polyester is 50 equivalents/ton or lower, and the content of sulfur atoms in the polyester is 0.0001-10 ppm, by the mass ratio to the polyester.
