An aluminum alloy brazing sheet has a quad-layer structure made of an outer filler material, intermediate layer material, core material, and inner filler material. The core material contains 0.5-1.6% of Mn, 0.10-0.50% of Cu, 0.05-0.50% of Mg, and 0.06-0.30% of Ti, and, as impurities, 0.5% or less of

The thickness of the intermediate layer material is 50 μm or more and no more than the thickness of the core material. The outer filler material and the inner filler material are Al--Si--Mg alloys, the outer filler material, preferably including at least one of 0.005-0.2% of In and 0.01-0.2% of Sn.
