The present invention addresses the problem of providing a moisture-permeable film for a total heat exchange element, which is used as a separator for constituting a total heat exchange element for a total heat exchanger, has excellent adhesion to a polyolefin microporous film, and has high moisture permeability, gas shielding properties, and moisture resistance. The moisture-permeable film for total heat exchange elements is characterized in that a moisture-permeable resin layer is provided on at least one surface of a polyolefin microporous film having a degree of air permeability resistance of 100 sec or more and a moisture permeability of 750 g/m2 * 24 hr or more. 本发明的课题在于，提供一种全热交换元件用透湿膜，其为用于构成全热交换器用的全热交换元件的隔板，与聚烯烃微多孔膜的粘接性优异，具有高的透湿性、气体遮蔽性和耐湿性。全热交换元件用透湿膜的特征在于，在透气阻力度为100sec以上、透湿度为750g/m2·24hr以上的聚烯烃微多孔膜的至少一个面设置透湿树脂层。
