Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a heat exchanger having a simple structure of high pressure resisting strength by reducing the number of soldered parts, and improving the heat exchanging performance by reducing heat resistance between a primary- side refrigerant and a secondary-side refrigerant, and effectively utilizing a heat transfer area, and also to provide a refrigerating cycle device using the heat exchanger. SOLUTION: This heat exchanger comprises a flat tube having a plurality of through holes for circulating the primary-side refrigerant, and a rectangular tube for circulating the secondary-side refrigerant, the flat tube is mounted in the rectangular tube, and an inner fin is mounted between the flat tube and the rectangular tube, or the fin is integrated with the flat tube to form the flat tube with the fin.
