PROBLEM TO BE SOLVED: To obtain a heat exchanger in which short circuit is prevented between the inflated fluid lead-in section and the inflated fluid discharge section of an end part flat hollow body and a defective brazed part can be readjusted easily. SOLUTION: A plurality of flat hollow bodies having an inflated fluid conducting section are arranged in parallel and an end part flat hollow body 3 is disposed on the outside of a flat hollow body at any one end. The end part flat hollow body 3 forms an inflated fluid lead-in section 19, having an inner aluminum plate and first and second outer aluminum plates 16, 17 brazed to the inner aluminum plate, between the inner aluminum plate and the first outer aluminum plate 16 and forms a fluid inlet 27 communicating with the fluid lead-in section 19 in the first outer aluminum plate 16. An inflated fluid discharge section 21 is formed between the inner aluminum plate and the second outer aluminum plate 17 and a fluid outlet 32 communicating with the fluid discharge section 21 is formed in the second outer aluminum plate 17. A plurality of positioning contact parts 24 are provided intermittently between the first outer aluminum plate 16 and the second outer aluminum plate 17.
