Abstract
Metallized layers are formed respectively on the surfaces to be joined of the ceramic members by performing metallized treatment on the surfaces, and then, these metallized layers are pressed against each other, and under pressure are diffusion-bonded at high temperature. A metal foil which can form a solid solution with the metallized layers can be interposed between the metallized layers before diffusion-bonding. This method can be used to manufacture an oxygen sensor element.
