<p>Ventilation apparatus, heat exchange apparatus, and heat exchange element, wherein the heat exchange element (21,22) includes a heat exchange sheet (211,221), a plurality of first ribs (212) arranged on one surface of the heat exchange sheet that guides a first gas flowing along the one surface of the heat exchange sheet, and a plurality of second ribs (222) arranged on the other surface of the heat exchange sheet and parallel to an arrangement angle of the first rib that guides a second gas flowing along the the other surface of the heat exchange sheet. The first (212) and second (222) ribs alternately support the heat exchange sheet (211,221). The heat exchange element may prevent the sag phenomenon of the heat exchange sheet without increasing duct resistance.
