The joined body 20 enters a porous ceramic 22 made of porous ceramics, a metal member 24 made of metal, and the pores 23 of the porous ceramic 22 and joins the porous ceramic 22 and the metal member 24 together. And an oxide ceramic joint 30 to be provided. The depth at which the oxide ceramic penetrates into the pores of the porous ceramic is preferably 10 μm or more, and more preferably 15 μm or more and 50 μm or less. In this joined body 20, a metal raw material is disposed between a porous ceramic and a metal member and fired in the atmosphere at a temperature of 400 ° C. or higher and 900 ° C. or lower, whereby the oxidized oxide ceramic of the metal raw material is porous ceramic. It can produce by the joining process which produces the junction part which penetrate | invaded in the pore of this. |
