PROBLEM TO BE SOLVED: To provide a heat exchanger capable of improving corrosion resistance of a fin while ensuring heat exchanging performance. SOLUTION: The heat exchanger for exchanging heat between intake air pressurized by a supercharger 3 and cooling air is provided with an inner fin 44, which is brought into contact with the intake air pressurized by the supercharger 3 to promote heat exchange between the intake air pressurized by the supercharger 3 and the cooling air. The inner fin 44 is constructed of a pure copper core material 44a and a tin-plated layer 44b formed on the surface of the core material 44a. COPYRIGHT: (C)2008,JPO&INPIT
