A method for producing a high temperature-resistant article comprises an assembling step of foaming an assembly of a first substrate and a second substrate with an adhesive layer interposed therebetween and comprising paste of powder of at least one carbide of niobium carbide, hafnium carbide, tantalum carbide and tungsten carbide; and a bonding step of heating the assembly to bond the first substrate and the second substrate by sintering, thereby obtaining a high temperature-resistant article comprising the assembly after sintering. Moreover, a method for producing a high temperature-resistant article comprises a coating step of coating a slurry comprising powder of at least one carbide of niobium carbide, hafnium carbide, tantalum carbide and tungsten carbide on a surface of a high temperature-resistant substrate; a drying step of drying the substrate after the coating step; and a film-forming step of heating the substrate after the drying step to form a carbide coating film on the surface of the substrate by sintering, thereby obtaining a high temperature-resistant article having the carbide coating film. A high temperature-resistant article of a complicated shape can be easily produced at low costs by these methods.
