PURPOSE:To provide an aluminum allay sheet excellent in weldability and capable of improving productivity without requiring treatment before welding and a large current at the time of welding. CONSTITUTION:This aluminum alloy sheet excellent in weldability is obtd. by sticking at least one side of an aluminum allay sheet with an aluminum alloy coated layer contg, by weight, 4 to 12% Si by 0.1 to 10mum thickness. The same allay coated layer may be incorporated, as allowable components, with one or more kinds among <=8% Mg, <=0.2% Zn, <=0.8% Fe, <=0.15% Mn, <=0.15% Cr, <=0.20% Ti, <=0.1% Bi and <=7% Cu.
