A heat exchanger, which maintains basic performance even in an environment repeatedly subjected to dew condensation, is provided. The heat exchanger is formed of a plurality of unit devices each including a heat exchanger plate, spacer ribs, and shielding ribs. The heat exchanger plate, the spacer rib and the shielding rib are integrally molded with resin. The spacer ribs keep the spacing between the heat exchangers, and the shielding ribs shield leakage of airflow. The unit devices are stacked each other to form airflow passages between the heat exchanger plates. The airflow passages allow a first airflow and a second airflow to pass therethrough and to exchange heat through the heat exchanger plates. The heat exchanger plate is made of a moisture permeable resin film having water-insolubility and flame retardant property, and the resin has water-insolubility and flame retardant property.
