PROBLEM TO BE SOLVED: To provide a total enthalpy heat exchanger producing the same performance even in an environment where dew condensation occurs repeatedly, and improves the efficiency of total enthalpy heat exchange. SOLUTION: In this total enthalpy heat exchanger, supply air and discharge air are caused to flow with a partition plate 4 between them, thus, sensible heat/latent heat exchange is conducted between the supply air and the discharge air via the partition plate 4. The partition plate 4 includes a non-woven fabric and a moisture-permeable gas-barrier material adherent thereto. The moisture-permeable gas-barrier material includes a water-insoluble hydrophilic polymeric material containing polyoxyethylene, and a moisture absorbent held in the hydrophilic polymeric material, and including at least one of deliquescent alkali metal salts and alkaline earth metal salts. The polyoxyethylene content in the hydrophilic polymeric material is 10-50 wt.%. COPYRIGHT: (C)2009,JPO&INPIT
