PROBLEM TO BE SOLVED: To provide a plate material for a can shell, which has an edge rate stably lowered to a low level (≥0%) even when the intermediate annealing step subsequent to hot-rolling annealing is omitted in producing it by cold-rolling a hot-rolled plate. SOLUTION: Use is made of the aluminum hot-rolled plate which is one containing 0.8-1.5% Mn, 0.5-1.5% Mg, 0.1-0.7% Fe, 0.05-0.5% Si, and the balance comprising Al and unavoidable impurities, wherein the amount of solute Mn is controlled at 0.12-0.38%, and the average crystal grain diameter is controlled at 20-50μm.
