Zusammenfassung:	OF THE DISCL SURE According to the present invention, a heat exchanger comprises a fin having a plurality of through holes. The plurality of through holes include mutually adjacent first and second through holes disposed on a side closest to a heating gas's inlet side. 5 The fin has a slit located between the first through hole and the second through hole and cut into the fin from an edge thereof located on the heating gas's inlet side to a side farther from the heating gas's inlet side than a reference line connecting a center of the first through hole and a center of the second through hole. Furthermore, the fin has at least one opening between the slit and the first and second through holes. The 10 opening includes a first opening having a portion located on the side farther from the heating gas's inlet side than the reference line.
