Provided is a heat exchange element that can suppress an increase in air-flow resistance by suppressing deflection of a partition member caused by a change in temperature and humidity, and that can improve total heat exchange efficiency by suppressing a decrease in heat-transfer area caused by increasing the number of spacing members. The present invention relates to a heat exchange element in which 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, and in which a primary air flow that passes along a 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, wherein the spacing member includes spacing ribs that maintain the spacing between the partition members being stacked adjacent to each other, and deflection sup
