PROBLEM TO BE SOLVED: To reduce thermal distortion of tubes in an integrated heat exchanger having two or more heat exchanger portions independent from each other, in one heat exchanger core. SOLUTION: This integrated heat exchanger comprises a core portion 3 having the plural tubes 1 arranged in parallel with each other to circulate a heat medium, and a fin 2 joined to outer surfaces of the tubes 1 for promoting heat exchange of the heat medium, and header tanks 4 extending in the direction orthogonal to the longitudinal direction of the tubes 1 at both longitudinal end portions of the tubes 1 and communicated with the tubes 1. Specific two tubes adjacent to each other among the plurality of tubes 1 are constituted as dummy tubes 10 in which the heat medium is not circulated, the header tanks 4 are divided with the portion between the two dummy tubes 10 set as a boudary, and an ATF cooler portion 31 and a condenser portion 32 are formed in the core portion 3 independently from each other with the two dummy tubes 10 set as the boundary.
