The present invention relates to a heat exchange element in which unit constituent members, each of which includes a partition member that has a heat-transfer property and a moisture permeability and a spacing member that holds the partition member with a predetermined spacing, are stacked and in which a primary air flow that passes along an upper surface side of the partition member and a secondary air flow that passes along an undersurface side of the partition member and crosses the primary air flow exchange heat and moisture through the partition member, wherein a detachment suppressing rib is provided on the opposite side of the spacing member when viewed from the partition member at a bonded portion between the partition member and the spacing member, and the partition member is sandwiched by the spacing member and the detachment suppressing rib.

Heat exchange element

Provided is a heat exchange element that suppresses an increase in air-flow resistance by suppressing deflection of a partition member caused by a change in temperature and humidity. The unit constituent members are stacked, each of which is formed of partition members that have heat-transfer properties and moisture permeability, and spacing members that hold the partition members. A primary air flow that passes along an upper-surface side of the partition member and a secondary air flow that passes along an undersurface side of the partition member cross each other so as to exchange heat and moisture via the partition member. The spacing member includes: spacing ribs that maintain the spacing between the partition members; and deflection suppressing ribs that have a height smaller than the spacing ribs so as to suppress deflection of the partition members.
