摘要： A resin composite film comprising a cellulose microfiber sheet and a resin, the resin composite film satisfying the following: (1) in a modulus mapping obtained by an examination of a cross-section with an AFM along the thickness direction, the fibers constituting the cellulose microfiber sheet have an average fiber diameter and a maximum fiber diameter, both calculated through image analysis, of 0.01-2.0 μm and 15 μm or smaller, respectively; and (2) at least one surface of the resin composite film has an overcoat resin layer having an average thickness, determined from the modulus mapping, of 0.3-100 μm.

摘要： Provided are: a resin-containing sheet in which not only the mechanical strength of a cellulose nanofiber nonwoven fabric but also the flexural resistance of a substrate are improved; and a structure and a wiring board which include the same. The resin-containing sheet includes: a specific cellulose nanofiber nonwoven fabric (11); a fixing agent (2) which fixes together fibers (1) in the cellulose nanofiber nonwoven fabric (11); and a resin (3) which is in contact with the cellulose nanofiber nonwoven fabric (11) and the fixing agent (2), wherein the storage modulus of the fixing agent (2) is higher than that of the resin (3). The structure is obtained by tightly adhering the resin-containing sheet to a substrate. The wiring board includes this structure.
