Abstract:
A total heat exchange element includes partitions disposed in a state of being opposed to each other, and a spacer portion keeping a space between the partitions and forming a passage between the partitions. The spacer portion has a laminate structure in which nonwoven fabric base layers including a nonwoven fabric base material are laminated on both sides of a paper layer. A first nonwoven fabric base layer that is the nonwoven fabric base layer of the spacer portion laminated on one side of the paper layer is joined to the partition opposed to the first nonwoven fabric base layer, and a second nonwoven fabric base layer that is the nonwoven fabric base layer of the spacer portion laminated on another side thereof is joined to the partition opposed to the second nonwoven fabric base layer. The element has the above-mentioned configuration and so can improve the humidity exchange efficiency.
