In the punching rivet method, it is possible to fasten the sheets without drilling. The joint has high strength and out-of-plane deformation of the joint is also small because of the rivet and the rivet holder that are peculiar to this method, hi this study, the punching rivet method was applied to joining of an acrylic resin sheet and an aluminum alloy sheet. The fastening condition and the strength of the joints made by the method were examined. From obtained results, it was possible to fasten an acrylic resin sheet and an aluminum alloy sheet by an aluminum alloy rivet. The acrylic resin sheet of the joint after joining had no crack and joint strength was high. It was certified that the punching rivet method became new joining method for a resin sheet and a metal sheet.
