Abstract
A heating apparatus has a spectral selective type heat radiating material having a high emissivity in a specific wavelength region. 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. The film is applied so it is possible to identify whether or not the heating apparatus is operating and to prevent the temperature of a surface of the heat radiant from rising excessively. The spectral selectivity of spectral emissivity is controlled by adjusting the thickness of the film of the spectral selective type heat radiating material.
