Abstract
An aluminum alloy sheet includes a function of heat joining in a single layer. The aluminum alloy sheet is formed of an aluminum alloy comprising: Si of 1.50 to 5.00 mass %; Fe of 0.01 to 2.00 mass %; and Mn of 0.50 to 2.00 mass %, with the balance being Al and inevitable impurities. In a heating test in which a temperature is raised from 300° C. to 400° C. at an average temperature rising rate of 60° C./min or less and held at 600±3° C. for 5±3 minutes, average grain size in a plane parallel to a rolled surface after the heating test is 370 μm or more, and an average number of grains in a sheet thickness direction after the heating test is 1.5 pieces or more.
