Abstract

There are provided an aluminum alloy plate having high strength and excellent corrosion resistance even though the plate is made thinner, and a heat exchanger formed thereof. In an aluminum alloy plate having a core material and a surface material cladded on at least one side of the core material, the surface material includes 0.030-0.30% by mass of Fe, 0.40-1.9% by mass of Mn, 0.40-1.4% by mass of Si, and 2.0-5.5% by mass of Zn, the rest comprises Al and inevitably included impurities, and an area ratio of an intermetallic compound containing Al and Mn to a whole surface of the surface material is 1% or less.
