Abstract
A heat-resistant member comprises: a substrate made of isotropic graphite; a single-layered dense low-emissivity layer covering part of surfaces of the substrate; and a single-layered or multi-layered dense high-emissivity layer covering all or part of the remaining surfaces of the substrate. The dense low-emissivity layer has an outermost surface with an emissivity of ε, and has a relative density of 97% or more. The dense high-emissivity layer has an outermost surface with an emissivity of ε(>ε), and has a high-density region with a relative density of 97% or more in any portion between the outermost surface and the interface with the substrate. Preferably, an emissivity difference (ε−ε) is 0.1 or more.
