Claim:
1. A pipe cover that is capable of covering an outer periphery of a pipe, the pipe cover comprising: a base that is formed of a tubular heat insulator, and a surface member that covers an outer surface of the base, a heat radiation section and a heat radiation-suppressing section being provided on an outer surface of the surface member, wherein the heat radiation section, formed of a ceramic thin film or a carbon thin film, is provided on a portion of the outer surface of the surface member, and the heat radiation-suppressing section is provided on a portion of the outer surface of the surface member opposite from the heat radiation section, and an emissivity of the heat radiation section at a wavelength of 2 to 15 μm being higher than an emissivity of the heat radiation-suppressing section at a wavelength of 2 to 15 μm, wherein the surface member is formed of a metal thin film, and the heat radiation-suppressing section is formed of a coating film of an antioxidant that suppresses oxidation of a metal that forms the surface member.
