Abstract: The present invention discloses a radiative cooling device and a method of manufacturing the same. Specifically, the radiative cooling device according to an embodiment of the present invention includes a reflective layer formed on a substrate and responsible for reflecting sunlight having wavelengths corresponding to ultraviolet, visible, and near-infrared regions; and a radiative cooling layer formed on the reflective layer and responsible for absorbing sunlight having a wavelength corresponding to a mid-infrared region and emitting the sunlight as heat, wherein the radiative cooling layer includes a first radiation layer including an uneven pattern; and a second radiation layer formed on the first radiation layer and having a refractive index different from that of the first radiation layer.
