An aluminum alloy sheet for brazing that is excellent in vacuum brazing and does not generate brazing, a method for producing the same, and a brazing sheet using the same. SO: 7.0-12.5 mass, Mg: 0.9-2.0 mass%, Fe: 0.05-0.60 mass%, Na: 0.5-30 massppm, P: 10 massppm or less, Ca : An area ratio in an arbitrary cross section of Mg 2 Si particles comprising an aluminum alloy containing 30 mass ppm or less, the balance being Al and inevitable impurities, and having an equivalent circle diameter of 1 to 3 μm is 0.5% or more And an aluminum brazing sheet using the aluminum alloy sheet.
