Abstract

A joined bodyincludes a porous ceramicmade of porous ceramic, a metal membermade of a metal, and a jointformed of an oxide ceramic that penetrates into poresof the porous ceramicand joins the porous ceramicto the metal member. The penetration depth of the oxide ceramic into the pores of the porous ceramic is preferably 10 μm or more, and more preferably 15 to 50 μm. The joined bodymay be produced through a joining step of forming a joint by placing a metal raw material between a porous ceramic and a metal member and firing the metal raw material in the air at a temperature in the range of 400° C. to 900° C., where an oxide ceramic produced by oxidation of the metal raw material penetrates into the pores of the porous ceramic in the joint.
