PROBLEM TO BE SOLVED: To provide a heat-resistant coating member which is a heat-resistant coating member for supporting and melting, sintering, or heat-treating a metal or a ceramic in a vacuum, an inert gas atmosphere, or a reducing atmosphere and is lightweight and excellently heat-resistant, resistant to reaction or welding with the metal or the ceramic, and capable of being repeatedly used many times. SOLUTION: The heat-resistant coating member is prepared by coating the surface of a carbonaceous material having a coefficient of thermal expansion of 2×10<SP>-6</SP>to 7.3×10<SP>-6</SP>/°C with an undercoat film containing at least Y and/or Hf and an upper layer film comprising an Al-containing Y-based oxide.
