The present invention provides a composition for producing a heat ray-shielding vinyl chloride film that can be applied to a usual vinyl chloride film production process, and a method for producing the same. A general formula tungsten oxide microparticles indicated by WO X, and / or, represented by the general formula M y WO Z, and a composite tungsten oxide fine particles having a hexagonal crystal structure, and a dispersing agent, A step of dispersing in an organic solvent to obtain a dispersion, a step of mixing the dispersion with a plasticizer for producing vinyl chloride film to obtain a mixture, and 5 wt% or less of the organic solvent from the mixture by vacuum distillation Until then, the composition for producing a heat ray-shielding vinyl chloride film was produced by removing it to obtain the composition for producing a heat ray-shielding vinyl chloride film.
