MOISTURE-RESISTANT COMPOSITE SHEET INCLUDING BASE MATERIAL SHEET LAYER CONTAINING FINE FIBER AND INORGANIC LAYER

摘要

To suppress a dimensional change in high temperature and high humidity environment of a sheet using a fine fiber into which a substituent having an electrostatic functionality and/or a three-dimensional functionality is introduced.SOLUTION: A composite sheet includes a base material sheet layer including a fine fiber (preferably, a fine fiber into which a substituent having an electrostatic functionality and/or a three-dimensional functionality is introduced) and an inorganic layer formed on at least one side of the base material sheet layer. The composite sheet may further have an organic layer on at least one side of the base material sheet layer.SELECTED DRAWING: None
