Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a heat exchanger with a fin allowing a smooth down-flow of water condensing on a fin surface along the fin when using the heat exchanger as an evaporator while improving heat exchange performance. SOLUTION: In a shape of the fin 21 of the front face side heat exchanger 20, a windward side edge part and a leeward side edge part are formed in nearly doglegged shapes respectively comprising two linear parts 22, 23 and 32, 33 wherein angles in cross parts of respective extensions having the same obtuse angles, and single curved parts 24, 34 respectively connecting the two linear parts 22, 23 and 32, 33. Thereby, because the single curved parts 24, 34 connect between the two linear parts 22, 23 and the 32, 33, the heat exchanger 20 does not require a bending process afterward, and a spacer necessary for the bending is not required as a matter of course.
