Abstract
A radiative cooling device and a radiative cooling method that effectively suppress ultraviolet light absorption. The radiative cooling device includes an ultraviolet reflection layer that reflects ultraviolet light UV, a light reflection layer that reflects visible light and infrared light, and an infrared radiative layer that radiates infrared light IR. Infrared light IR is radiated form a radiative surface. The ultraviolet reflection layer, the infrared radiative layer and the light reflection layer are laminated in this order as viewed from the side of the radiative surface.
