Sheet for heat exchange element

The present invention addresses the problem of providing a sheet for heat exchange elements, which has high gas shielding properties, high mildew resistance, and water resistance that can be used even under high humidity conditions. A sheet for heat exchange elements, which has a laminated structure of a porous base material and a resin layer, and which is characterized in that the sheet for heat exchange elements has a first surface and a second surface, the outermost layer on the first surface side of the sheet for heat exchange elements is the resin layer, and the resin layer contains a polyvinyl pyrrolidone and/or a vinyl pyrrolidone copolymer. The resin layer contains a mildew inhibitor. 本发明的课题在于，提供具有高气体遮蔽性、具有高抗霉性、具有即使在高湿度条件下也能够使用的耐水性的热交换元件用片材。热交换元件用片材，其具有多孔质基材和树脂层的层叠结构，前述热交换元件用片材具有第一面和第二面，前述热交换元件用片材的前述第一面侧的最表层是树脂层，前述树脂层含有聚乙烯基吡咯烷酮和/或乙烯基吡咯烷酮共聚物，前述树脂层含有防霉剂。
