PROBLEM TO BE SOLVED: To provide a highly corrosion resistant aluminum clad material for a heat exchanger suitably used for a tube material of a heat exchanger, particularly of an automobile heat exchanger such as a piping material (extruded clad pipe material) connected with a heat exchanger, a tube material of an automobile heat exchanger made of an aluminum alloy such as an evaporator, a condenser, a radiator, a heater core, an intercooler and an oil cooler joined by vacuum brazing or inert gas atmosphere brazing using fluoride-based flux, and a tube material for a heat exchanger connected by a non-brazing system such as adhesion, welding and soldering. SOLUTION: The aluminum clad material is obtained by cladding at least one side of a core material composed of aluminum with a sacrificial anode material or obtained by cladding one side of a core material with a sacrificial anode material and cladding the other side with a brazing filler metal. The sacrificial anode material is composed of pure aluminum having an aluminum purity of≥99.9% or an aluminum alloy at least containing Mg, wherein the total content of Al and Mg is≥99.9%.
