Abstract
A radiator includes a heat radiation ceramic material. The heat radiation ceramic material includes a first metal oxide as a principal component, the first metal oxide being a metal oxide having a wurtzite crystal structure; and a second metal oxide as a metal oxide having an average emissivity higher than or equal to 70% in a wavelength range of 3 μm to 25 μm inclusive. At least one of a trivalent metal-doped metal oxide where some metal atoms of the first metal oxide are substituted with trivalent metal atoms and a monovalent metal-doped metal oxide where some metal atoms of the first metal oxide are substituted with monovalent metal atoms is included as the second metal oxide.
