Abstract
A thermal radiator (21) includes first carbon nanotubes (CNTs) in which excitons produced based on energy from an energy source have energy consistent with a wavelength region within a range from the visible region to the near-infrared region, wherein the chemical potential of the excitons is maintained higher than zero.
