The metal plate joining method for using electric resistance welding in combination with an adhesive and joining at least two or more metal plates includes the steps of: continuously coating the adhesive on at least one flange out of flanges respectively formed in the plurality of the metal plates; then superimposing the one flange on the other flange; making a protrusion formed in any one flange out of the two flanges abut with the other flange; and forming a gap between the two flanges at a flange inner edge side of the protrusion, wherein while suppressing a move of the adhesive to a flange outer edge by the protrusion, the two flanges push the gap and are welded by the electric resistance welding.
