    摘要： There is provided a heat exchanger and a fin member for the heat exchanger that can suppress occurrence of hollow corrosion in a fin and hold cooling performance for a long period of time under a high corrosion environment. The heat exchanger includes an aluminum tube through which a working fluid circulates and an aluminum fin which is bonded to the tube. The fin has a region B around a grain boundary, and a region A around the region B. In the region B, 5.0×10 4 pieces/mm 2 less of Al-Fe-Mn-Si based intermetallic compound, each of which has equivalent circle diameters of 0.1 to 2.5 µm, and in the region A, 5.0×10 4 pieces/mm 2 to 1.0×10 7 pieces/mm 2 of Al-Fe-Mn-Si based intermetallic compound, each of which has equivalent circle diameters of 0.1 to 2.5 µm.
