PROBLEM TO BE SOLVED: To provide a heat exchanger 100 which improves the loadability, while realizing high pressure resistance. SOLUTION: A heat tank 130 is composed of a tank plate 131 formed by rolling up a plate material provided with two or more slots 131a for inserting and joining two or more flat tubes 111, into the oval cylindrical shape, and a tank reinforcement member 132 formed by an oval block inserted and joined inside of the tank plate 131. Whereby even the tank plate 131 formed by rolling up the plate material into the oval cylindrical shape can be provided with high pressure resistance by inserting and joining the tank reinforcement member 13 of the block. Further an oval plane part of the header tank 130 is exposed to an end part of a core part 110, and an outer hull part of the heat exchanger 100 is formed by a plane, which improves the loadability in mounting the heat exchanger 100 in an air conditioner casing.
