Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a heat exchanger which can improve a heat exchanging efficiency, by improving the shape and the setting conditions of refrigerant tubes provided in the heat exchanger. SOLUTION: A heat exchanger comprises a number of fins 52 which are provided in parallel with a given interval therebetween so as to pass air therethrough, and refrigerant tubes 51a, 51b through which an operational fluid flows and which are inserted into the individual fins 52 at a right angle in two rows or more. Each of the refrigerant tubes 51a, 51b has a hollowed elliptic shape, and is so arranged that a major axis a thereof and the end portion of the fin 52 at an air inflow side make an acute angle θ therebetween. Desirably, the angle θ between the major axis a of the individual refrigerant tubes 51a, 51b and the end portion of the fin 52 at the air inflow side should be 45-85 deg..
