Provided are an aluminum cladding material having excellent corrosion resistance, a production method therefor, an aluminum cladding material for heat exchangers having excellent corrosion resistance, a production method therefor, an aluminum heat exchanger using said aluminum cladding material for heat exchangers, and a production method therefor. Said aluminum cladding material comprises an aluminum alloy core material and a sacrificial anode material layer clad on at least one surface thereof. The sacrificial anode material layer comprises an aluminum alloy containing 0.10 mass% or more and less than 1.50 mass% Si, 0.10 to 2.00 mass% Mg. Present therein is 100 to 150000 pieces/mm 2 of Mg-Si-based crystallized product having a circle-equivalent diameter of 0.1 to 5.0 µm, 7 pieces/mm 2 or less of Mg-Si-based crystallized product having a circle-equivalent diameter of more than 5.0 µm and 10.0 µm or less in the sacrificial anode material layer.
