Stage: PROBLEM TO BE SOLVED: To provide a brazing sheet that can exhibit exceptional brazing performance when an aluminum material is brazed without using flux in an inert gas atmosphere such as a nitrogen gas atmosphere.SOLUTION: The present invention provides an aluminum alloy brazing sheet used in brazing within an inert gas atmosphere, the aluminum alloy brazing sheet having a core material and a brazing material with which one or both surfaces of the core material are clad, the core material being formed from an aluminum alloy that contains 0.10-0.50 mass% of Mg, the balance being aluminum and unavoidable impurities, the brazing material being formed from an aluminum alloy that contains 6.00-13.00 mass% of Si and is limited to less than 0.05 mass% of Mg, the balance being aluminum and unavoidable impurities, and the Mg integration value from the surface of the brazing material to a depth of 30 nm therefrom being 150 atm%xnm or less.SELECTED DRAWING: None (Grant)
