It is an object to provide a heating apparatus that uses a spectral selective type heat radiating material and has improved safety and energy efficiency, and the present invention is a heating apparatus that uses a spectral selective type heat radiating material having a high emissivity in a specific wavelength region, wherein a film of the spectral selective type heat radiating material is formed on a surface of a heat radiant while leaving at least one region of the surface of the heat radiant with nothing formed thereon, having property capable of identifying whether or not the heating apparatus is operating and preventing the temperature of a surface of the heat radiant from rising excessively, and also is a heating apparatus that uses a spectral selective type heat radiating material, wherein the spectral selectivity of spectral emissivity is controlled by adjusting the thickness of the film of the spectral selective type heat radiating material.
