Abstract: A core material contains Mn: 0.3-2.0 mass % (hereinafter, abbreviated to %), Si: 1.5% or less, Fe: 0.1-1.0% and Cu: 0.05-1.0%, and comprises a remainder Al and unavoidable impurities, and the sacrificial anode material contains Fe: 0.05-1.0% and Zn: 0.5-5.0%, and comprises a remainder Al and unavoidable impurities. A potential at the joint section between the header pipe and the tube is lower by 30 mV or less than potentials at the header pipe surface and the tube surface, and the potential at the joint section is lower by 30-100 mV than a potential at a position in a depth of one quarter of the overall thickness from the header pipe surface and a potential at a position in a depth of one quarter of the overall thickness from the tube surface.
