摘要： The present invention addresses the problem of providing a sheet for heat exchange elements which has high gas-barrier properties, has high fungal resistance, and has water resistance such that the sheet can be used even under high-humidity conditions. The sheet for heat exchange elements has a multilayer structure comprising a porous base and a resin layer, and has a first surface and a second surface. The outermost layer of the sheet for heat exchange elements on the first-surface side is the resin layer. The resin layer comprises polyvinylpyrrolidone and/or a vinylpyrrolidone copolymer, and contains a fungicide.
