PROBLEM TO BE SOLVED: To miniaturize a device by improving an air supply flue and an air exhaust flue of a heat exchanger part far from an air supply blower and an air exhaust blower. SOLUTION: In this heat exchanging ventilating device comprising the air supply flue 5 partially composed of one of fluid passages 3 of the stacked hexagonal heat exchanger 1 incorporated in a hexagonal casing 2, and allowing the airflow to move from an outdoor side to an indoor side by the air supply blower 4, and the air exhaust flue 8 completely independent from the air supply flue 5, partially composed of the other fluid passage 6 of the heat exchanger 1, and allowing the airflow to move from the indoor side to the outdoor side by the exhaust blower 7, the air supply flue 5 and the air exhaust flue 8 are formed along faces facing to the fluid passages 3, 6 of the heat exchanger 1, and the air supply flue 5 and the air exhaust flue 8 are constituted to be wide near the blowers and gradually narrowed in accordance with the separation from the blowers.
