Abstract
In an attachment structure in which a flange 2 of a heat exchanger and a casing 3 form metal touch 12, a protruding step surface is formed at the hole edge portion of the flow path hole of the flange of the heat exchanger, which projects toward the casing side from the surface of the metal touch. Thereby, the flange is firmly press-contacted with the casing, and the fluid is prevented from leaking out of the hole edge of the flow path hole.
