The present invention relates to a radiative cooling paint consisting of ceramic fine particles as pigments, a polymer resin as a binder, and a solvent. According to the present invention, a substrate is coated with the radiative cooling paint, and then a paint film layer is formed. The paint film layer performs a radiative cooling function by preventing energy inflow from incident sunlight by maximizing reflection of incident sunlight; minimizing absorption of incident sunlight; and maximizing emission of long-wavelength infrared light corresponding to 8 m to 13 m and increasing energy discharge through emission of long-wavelength infrared light, and pores with a volume of 3% to 50% are formed inside the paint film layer to enhance reflection of incident sunlight without reducing emission of long-wavelength infrared light.
