An integrated heat exchanger is constituted by different kinds of heat exchangers such as a radiator for use in engine-cooling systems snd a condenser for use in air-conditioning systems which is low in manufacturing cost, small in thickness, easy in maintenance and/or replacement and small in air pressure loss. The heat exchanger includes a first heat exchanger (2) and a second heat exchanger (3). A fitting dented portion (6) is provided at one of a bottom surface of the first heat exchanger (2) and an upper surface of the second heat exchanger (3), and a fitting protruded portion (5) is provided at the other thereof, and wherein the fitting protruded portion (5) is fitted in the fitting dented portion (6), whereby the first heat exchanger (2) is integrally conected to the upper surface of the second heat exchanger (3).
