PROBLEM TO BE SOLVED: To provide a tank of a heat exchanger reducing a clearance between a partitioning plate and an inner wall of a sheet metal or a capsule, and effectively preventing the impairing of the heat exchanging efficiency caused by the leakage of the fluid from the clearance. SOLUTION: This heat exchanger 1 comprises an upper tank 2 and a lower tank 3 vertically arranged in parallel with each other, the upper tank 2 has a structure formed by abutting and joining the sheet metal 4 and the sheath-shaped capsule 5. The partitioning plate 7 having the shape same as the transverse section of the upper tank 2 is mounted in the upper tank 2. The fixing of the partitioning plate 7 to the upper tank 2 is achieved by fitting insertion parts 71, 72 projected from a lower side of the partitioning plate 7 into both corner slits 43, 44 formed at both corners of a bottom plate part 41 of the sheet metal 4 orthogonal to the longitudinal direction, and brazing them.
