The present invention provides a heat insulation sheet (100) laminated on the upper surface of an upper plate of a vehicle, the heat insulation sheet being provided with: a low-emissivity coating layer (103) having a white color; a base material sheet (101) on which the low-emissivity coating layer (103) is laminated; and a colored infrared transparent layer (104) which is laminated closer to the sunshine side than the low-emissivity coating layer (103) and transmits infrared rays. Since the low-emissivity coating layer (103) has a white color, the reflectivity of sunlight is high. Therefore, solar heat can be effectively reflected. Furthermore, by setting the color of the colored infrared transparent layer (104) to the vehicle body color of the vehicle or a color similar to the vehicle body color, the heat shield sheet (100) can be made inconspicuous even when the heat shield sheet (100) is disposed in the vehicle.
本发明提供一种层叠于车辆的上板的上表面的隔热片(100),上述隔热片具备:低辐射率涂料层(103),为白色系的颜色;基体材料片(101),层叠有低辐射率涂料层(103);以及有色红外线透明层(104),层叠在比低辐射率涂料层(103)靠日照侧,透过红外线。由于低辐射率涂料层(103)是白色系的颜色,因此太阳光的反射率高。因而,能够有效地反射太阳热量。另外,通过将有色红外线透明层(104)的颜色设为车辆的车身颜色或者与车身颜色类似的颜色,即使在将隔热片(100)配置于车辆的情况下,也能够使隔热片(100)不显眼。
