Abstract
Provided is an aluminum alloy clad material including an aluminum alloy core material, an intermediate layer material that is clad on one surface of the core material, and a first brazing filler metal that is clad on a surface of the intermediate layer material, the surface not being on the core material side, wherein the core material, the intermediate layer material, and the first brazing filler metal each include an aluminum alloy having a predetermined composition, the existence density of Al—Mn based intermetallic compounds having a circle-equivalent diameter between 0.1 and 1.0 μm inclusive in the intermediate layer material before brazing heating is at least 1.0×10pieces/mm, and the existence density of Al—Mn based intermetallic compounds having a circle-equivalent diameter between 0.1 and 1.0 μm inclusive in the intermediate layer material after brazing heating is at least 1.0×10pieces/mm. Further provided is a method for producing the aluminum alloy clad material.
