TOTAL HEAT EXCHANGE ELEMENT

This total heat exchange element (30) comprises a plurality of partition plates (31) each having: a substrate (32) having a first main surface (32a) and a second main surface (32b); and a moisture permeable membrane (33) provided on the first main surface (32a) side of the substrate (32), the partition plates being arranged with a gap therebetween. Between the plurality of partition plates (31), a first flow passage (36) through which air flows and a second flow passage (37) through which air having a higher steam pressure than that in the first flow passage (36) are alternately formed. In the plurality of partition plates (31), the first main surface (32a) of the substrate (32) is directed toward the first flow passage (36), and the second main surface (32b) of the substrate (32) is directed toward the second flow passage (37). 全热交换元件(30)包括多个隔板(31)，多个隔板(31)分别具有基材(32)和透湿膜(33)，基材(32)具有第一主面(32a)和第二主面(32b)，透湿膜(33)设置在基材(32)的第一主面(32a)侧，多个隔板(31)彼此留有间隔地排列。在多个隔板(31)之间交替地形成有供空气流动的第一流路(36)、和供与该第一流路(36)中的空气相比水蒸气压力高的空气流动
