Zusammenfassung:	PROBLEM TO BE SOLVED: To provide an aluminum alloy brazing sheet which can improve erosion resistance while maintaining strength after brazing, brazing property, formability and corrosion resistance, or the like, even when Mg is added to a core material.SOLUTION: The aluminum alloy brazing sheet is an aluminum alloy brazing sheet where Al-Si-based or Al-Si-Zn-based brazing material is cladded on at least one face of the core material. The core material contains, by mass%, 0.3 to 1.0% Si, 0.6 to 2.0% Mn, 0.3 to 1.0% Cu, 0.15 to 0.5% Mg, 0.05 to 0.25% Ti, and the balance being Al and unavoidable impurities, and the density of a Mg-Si, Al-Mg-Cu and Al-Cu-Mg-Si intermetallic compound having a particle diameter of less than 0.5 μm in the core material is 10,000 pieces/mmor higher.
