Abstract: Embodiments relate to a method for manufacturing a heat-shielding film in which a heat-shielding material has been well dispersed in a polyvinyl chloride resin. According to one embodiment, the method for manufacturing the heat-shielding film includes (1) mixing a polyvinyl chloride resin composition (P) containing the polyvinyl chloride resin (A) using a blender, and (2) adding and further mixing the heat-shielding material with the mixture obtained in step (1 The heat-shielding material contains at least antimony-doped tin oxide micro-particles (B) in an amount in which the mass ratio of the polyvinyl chloride resin (A) to antimony-doped oxidized tin micro-particles (B) is 100 parts by mass to 1.5 to 15 parts by mass. The heat-shielding material is composed of antimony-doped oxidized tin micro-particles (B) alone.
