RESIN-CONTAINING SHEET, AND STRUCTURE AND WIRING BOARD USING SAME

摘要

Provided are a resin-containing sheet whereby bending resistance of a substrate is enhanced while chemical strength of a cellulose nanofiber nonwoven fabric is enhanced, and a structure and wiring board which use the same. A resin-containing sheet having a specific cellulose nanofiber nonwoven fabric (11), a fixing agent (2) for fixing together fibers (1) in the cellulose nanofiber nonwoven fabric (11), and a resin (3) in contact with the cellulose nanofiber nonwoven fabric (11) and the fixing agent (2), the storage modulus of the fixing agent (2) being higher than the storage modulus of the resin (3). A structure obtained by bonding the resin-containing sheet to a substrate. A wiring board having the structure.
