Abstract
An infrared light radiation device includes a radiation unit and a condenser. The radiation unit includes a heater and a metamaterial structure. The metamaterial structure is able to radiate, when heat energy is input from the heater, infrared light having a peak wavelength of a non-Planck distribution. The condenser includes at least one condensing lens that concentrates and transmits toward outside the infrared light radiated from the radiation unit.
