A joint structure of a first member includes a substrate made of ceramics and a metal embedded member embedded in the substrate, in which a part of the metal embedded member is exposed to a joint surface of the first member, and a second member made of metal. The joint structure includes: an intermediate insertion member interposed between the joint surface of the first member and the second member; a first joint layer which joins the joint surface of the first member and the intermediate insertion member; and a second joint layer which joins the second member and the intermediate insertion member. In the joint structure, the intermediate insertion member is made of a laminated member of a plurality of ceramics layers and at least one metal layer interposed between respective ceramics layers.
