Abstract
A heat radiation device includes a heat source, a meta-material structure layer arranged on a front surface side of the heat source and configured to radiate radiant energy in a specific wavelength range by converting heat energy inputted from the heat source into the radiant energy in the specific wavelength range, and a rear-surface metal layer arranged on a rear surface side of the heat source. An average emissivity of the rear-surface metal layer is smaller than an average emissivity of the meta-material structure layer.
