Abstract: An aluminum alloy brazing sheet, a manufacturing method therefor, and a manufacturing method for an automotive heat exchanger. The aluminum alloy brazing sheet includes an aluminum alloy core material, a first brazing material that is clad to one surface of the core material, and a second brazing material that is clad to the other surface of the core material. The core material, the first brazing material, and the second brazing material each include a respective prescribed aluminum alloy. A count of an Al—Si—Fe intermetallic compound having an equivalent circle diameter of 0.5 to 80.0 μm in the second brazing material is less than or equal to 2,000 particles per mm2.
