Air around an outer periphery of each of the tubes is heat-exchanged by the hot water passing through thetubes 101, thereby the air is heated. - Here, it is required that if the
heat exchanger 100 is installed in the automobile, theheat exchanger 100 is disposed in a limited in-car space in the automobile. If the in-car space S has a trapezoidal shape, the heat exchanger is disposed as shown in FIG.3. - However, in the above-mentioned
conventional heat exchanger 100, because theinlet pipe 107 and theoutlet pipe 108 must be disposed in a significantly projected state from a side surface of theheat exchanger 100, only a heat exchanger having a smaller width W than a length L of the trapezoidal in-car space S can be merely disposed.

- Inclined sections configured to incline to a longitudinal direction of the tubes are provided at two locations on the other side header tank part, and the inlet pipe connecting part and the outlet pipe connecting part are provided on the inclined sections, respectively.
- If the number of the tubes which communicate with the inlet tank chamber and are outward flow paths is B1 and the number of the tubes which communicate with the outlet tank chamber and are homeward flow paths is B2, a relation between B1 and B2 is set to be B1 > B2.
