PROBLEM TO BE SOLVED: To provide a heat exchanger capable of improving the feedable performance of an adhesive without being affected by the variations in the viscosity and the setting temperature of the adhesive and the like. SOLUTION: A heat exchanger has a core plate 140 that is coupled with the open end surfaces 111 and 121 of tanks 110 and 120, and the end 151 of a tube 150 is fitted in a hole 141 provided in this core plate 140. The circumference of the fit part 160 of the tube 150 is sealed by a thermosetting adhesive 170. In such a heat exchanger, a plate surface 142 provided with the hole 141 is provided with a tilt 143 that is tilted to a virtual surface orthogonal to the longitudinal direction of the tube 150. The adhesive 170 has such a property that its viscosity drops once due to the rise in temperature and increases afterwards. Moreover, the tilt part 143 is tilted in the major axis direction of the cross section of the tube 150.
