To provide a heat exchanger used in a total enthalpy heat exchange type ventilation device, capable of keeping basic performance even in an environment where dew condensation repeatedly occurs.
In this heat exchanger 1 wherein an unit element 2 is formed by integrally molding spacial ribs 5a, 5b for keeping a space between a heat transfer plate 3a and a heat transfer plate 3a, and shielding ribs 6a, 6b for shielding the leakage of airflow, with a resin, the plurality of unit elements 2 are stacked to form a ventilation flue 4 between the heat transfer plates 3a, and the primary airflow and the secondary airflow are circulated to the ventilation flue 4 to exchange heat through the heat transfer plates 3a, the heat transfer plate 3a is composed of a water insoluble flameproof permeable resin film 7a, and the resin is composed of the water insoluble flameproof resin.
