A ceramic member is provided including a base including an alumina sintered body, an yttria sintered body formed on the alumina sintered body, an intermediate layer including yttrium and aluminum formed between the alumina sintered body and the yttria sintered body, and a metallic member buried in the intermediate layer of the base.
