The object of the present invention is to provide an excellent total heat exchanging element paper and a total heat exchanging element which are excellent in heat transferability, water vapor permeability and gas barrier properties and cause no mixing of supplied air and discharged air. The present invention provides a total heat exchanging element paper using a paper made using mainly a natural pulp beaten to a Canadian modification freeness of not more than 150 ml, a substantially non-porous total heat exchanging element paper comprising a substantially non-porous cellulosic base which contains a moisture absorbing agent, a non-porous total heat exchanging element paper having a high gas barrier property which has a thickness of not more than 100 &#x3bc;m and a carbon dioxide permeation constant specified in JIS K7126 of not more than 5.0&#xd7;10mol&#xb7;m/m&#xb7;s&#xb7;Pa, and a non-porous total heat exchanging element paper having a high enthalpy exchangeability which has a water vapor permeability specified in JIS Z0208 of not less than 1000 g/m&#xb7;24 Hr at 20&#xb0; C. and 65% RH.

The object of the present invention is to provide a heating regeneration type organic rotor member which comprises a honeycomb structural body capable of being continuously regenerated by heating upon rotational driving and remarkably improved in mechanical strength by using a fiber substrate essentially composed of organic fibers and which can efficiently adsorb and remove moisture and odor components in the air by the action of moisture adsorbent and active carbon carried on the fiber substrate, and to provide a method for producing the same. According to the present invention, there is provided a heating regeneration type organic rotor member which is produced by forming a functional substrate into a honeycomb structural body, the functional substrate comprising a fiber substrate containing organic fibers as an essential component and carrying thereon a moisture adsorbent and an active carbon.
