PROBLEM TO BE SOLVED: To provide an infrared ray-shielding material in which particles hardly aggregate and the oxidation of the particle surface is suppressed, which has high transparency and a small haze value, and with which an infrared ray-shielding film having a high infrared ray-shielding rate is formed, and to provide a coating material for shielding infrared rays, which contains the infrared ray-shielding material, an infrared ray-shielding film formed by using the coating material for shielding infrared rays, and an infrared ray-shielding base material in which an infrared ray-shielding film is provided on a transparent base material.SOLUTION: The infrared ray-shielding material contains infrared ray-shielding material particles, in each of which the surface is covered with an organic substance, and in the infrared ray-shielding material, the carbon content in the organic substance covering each infrared ray-shielding material particle is 0.2-5 mass%. The coating material for shielding infrared rays contains the infrared ray-shielding material. The infrared ray-shielding film is formed by using the coating material for shielding infrared rays, and in the infrared ray-shielding base material, an infrared ray-shielding film is provided on a transparent base material. |
