A Joint structure for members of different kinds of metals comprises a first member formed from a metal sheet, and a second member formed from a metal sheet having a coefficient of thermal expansion greater than that of the metal sheet for the first member, wherein the first member and the second member are superimposed on each other and spot-joined together at a plurality of positions in a first direction, and the second member has a bead portion extending along a second direction orthogonal to the first direction, at a position between adjacent ones of the spot-joined points. |
