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. |
