PROBLEM TO BE SOLVED: To provide a heat exchange element capable of unvariably providing high heat exchange efficiency performance. SOLUTION: This heat exchange element 1 has an opposed part 5 of opposing an supply air duct 3 ventilating supply air A and an exhaust air duct 4 ventilating exhaust air B via heat transfer paper 2, for exchanging heat by ventilating the supply air A and the exhaust air B every one stage of a ventilation passage formed between a plurality of heat transfer paper 2 laminated at a predetermined interval, and an orthogonal part 6 orthogonally arranging the supply air duct 3 ventilating the supply air A and the exhaust air duct 4 ventilating the exhaust air B via the heat transfer paper 2, and also has a shielding rib 9 preventing leakage of an air current from a part except for an inflow port 7 and an outflow port 8 of the supply air A and the exhaust air B. The heat exchange element can be provided for eliminating a variation in the heat exchange efficiency performance even when deformation of the heat transfer paper is caused by influence such as humidity, by arranging the heat transfer paper 2 so that the hoop direction C of the heat transfer paper 2 becomes perpendicular to the flowing direction for ventilating the supply air A and the exhaust air B of the opposed part 5.
