PROBLEM TO BE SOLVED: To provide a resin film with an adhesive layer, capable of suppressing generation of interference fringe while satisfying oligomer prevention and scratch resistance required for an oligomer prevention layer even when the oligomer prevention layer is thinned, and having good adhesion with the adhesive layer.SOLUTION: There is provided a resin film 1 with the adhesive layer, formed by laminating a first transparent resin film 10, an oligomer prevention layer 11 and the adhesive layer 13 in this order, wherein the oligomer prevention layer 11 is a cured layer formed by curing a composition containing a curable compound and inorganic oxide particles, the thickness of the oligomer prevention layer 11 is ≥120 nm, the refractive index difference between the oligomer prevention layer 11 and the adhesive layer 13 is ≤0.04, and the anchoring force between the oligomer prevention layer 11 and the adhesive layer 13 is ≥1 N/25 mm.
