PROBLEM TO BE SOLVED: To solve the problem that, when the movement of latent heat is intended between two air streams flowing on top and back surfaces of a partition member, not only a moisture absorbent layer, but also a flame retardant layer are present in a moving direction of moisture contents, and thus that, even when the moisture absorbent layer adsorbs the moisture contents, the flame retardant layer then becomes resistant to the movement of the moisture contents to reduce the amount of the movement of the moisture contents in that portion, resulting in the reduction in moisture permeability of the partition member. SOLUTION: A partition member 2 and an interval holding member 3 are configured so that a moisture permeability imparting portion which imparts moisture permeability and a flame retardancy imparting part which imparts flame retardancy do not overlap with each other in one member. For example, the partition member 2 is defined as the moisture permeability imparting portion which imparts moisture permeability and the interval holding member 3 is defined as the flame retardancy imparting portion which imparts flame retardancy.
