PROBLEM TO BE SOLVED: To provide a heat ray-shielding transparent substrate that is produced by forming a heat ray-shielding film exhibiting excellent heat shielding properties and having an appropriate color tone on the surface of a transparent substrate, to provide an automobile that is mounted with the heat ray-shielding transparent substrate as a window material and to provide a building structure that has the heat ray-shielding transparent substrate used as a window material.SOLUTION: The heat ray-shielding film comprises a composite tungsten oxide fine particle, a selective wavelength absorption material and an inorganic binder. The selective wavelength absorption material has a transmission profile that the transmittance of light having a wavelength of 550 nm is 90% of more and that the transmittance of light having a wavelength of 420 nm is 40% or less when the transmittance of light having a wavelength of 460 nm is 90% or more. 【課題】優れた遮熱特性を発揮し、かつ適切な色調を持った熱線遮蔽膜を透明基材の表面に形成することで作製された熱線遮蔽透明基材、当該熱線遮蔽透明基材が窓材として搭載されている自動車、および当該熱線遮蔽透明基材が窓材として使用されている建造物を提供する。【解決手段】複合タングステン酸化物微粒子と、選択波長吸収材料と、無機バインダーとを含有する熱線遮蔽膜であって、前記選択波長吸収材料は、波長５５０ｎｍの光の透過率が９０％以上であり、かつ波長４６０ｎｍの光の透過率が９０％以上であるときの波長４２０ｎｍの光の透過率が４０％以下の透過プロファイルを有する線遮蔽膜を提供する。【選択図】なし
