PROBLEM TO BE SOLVED: To facilitate the maintenance of the heat exchange capacity of a leeward heat exchanger, in two more more heat exchangers which are arranged in parallel to be orthogonal to the direction of ventilation. SOLUTION: This is a heat exchanger where, in two or more heat exchangers arranged in parallel windward and leeward in the direction of ventilation, the height hc of the tube of one heat exchanger arranged windward in the direction of ventilation is smaller than the height hr of the tube 4 of other heat exchanger arranged leeward (hc<hr), and two more heat exchangers are constituted integrally by common members.
