PROBLEM TO BE SOLVED: To provide a method of joining silicon carbide porous ceramics by which the porous ceramics each comprising silicon carbide and having many communicating pores through which a liquid is permeated are uniformely joined with soldering while preventing the infiltration of the soldering into the pores of the porous part without damaging the characteristics of the porous ceramic such as air permeability or water permeability and a joined memeber obtained by the same. SOLUTION: An oxide film is formed on the inner and outer surfaces of the silicon carbide porous ceramics by heat-treating at≥750°C and≤1,700°C and one silicon carbide porous ceramic is joined to another silicon carbide on the oxide film formed surfaces each other with a silicon based soldering.
