As conventional heat exchange modules, adsorptive agents of an inorganic type such as silica gel, zeolite, active alumina, active carbon and molecular sieve have been used. While these adsorptive agents have characteristics of high moisture absorptive ability and easy handling, they have problems of durability, regenerating temperature and generation of bacteria or fungi. An object of the present invention is to solve these problems which are noted in the inorganic adsorptive agents and to provide a heat exchanger module of a energy conservation type having a high heat exchange efficiency and a method for the manufacture thereof. The present invention is a heat exchange module of a sorptive type, characterized in that, a moisture absorptive layer in which a sorptive agent of an organic polymer type comprising organic polymer having hydrophilic polar group and cross-linking structure in a molecule is an essential component, saturated moisture absorbing rates at 20° C. and 65% RH and 90% RH are not less than 20% by weight and not less than 40% by weight, respectively and the difference in the saturated moisture absorbing rates under such a condition is not less than 20% by weight is formed on a metal surface having excellent heat conductivity.
