▎ 摘　　要

NOVELTY - Graphene bonded body having a structure comprises a graphene-containing carbonaceous member containing a graphene aggregate and a member to be joined are joined, junction interface between the graphene-containing carbonaceous member and the member to be joined, an active metal compound layer formed on the joint surface of the graphene-containing carbonaceous member, and a tin-concentrated layer having a tin concentration of greater than or equal to 1 %mass formed on the graphene-containing carbonaceous member side, where the thickness of the metal compound layer is 0.05-3 mu m. USE - As graphene bonded body. ADVANTAGE - The graphene bonded body has no peeling even under a cold cycle load and excellent cold cycle reliability.
