An object of the present invention is to provide a pre-coated fin material that is excellent in hydrophilic sustainability of fins, can be joined between a fin and an aluminum tube without separately supplying a brazing material, and can produce a heat exchanger excellent in joinability, and To provide a heat exchanger using the pre-coated fin material. A pre-coated fin material having an aluminum alloy plate and a coating film formed on the surface thereof, and a heat exchanger using the same. The aluminum alloy plate 11 contains Si: 1 to 5% by mass, and the remainder has chemical components composed of Al and inevitable impurities. The Si content in the coating film 12 is 10 to 300 mg / m2. [Selection] Figure 1 |
