PROBLEM TO BE SOLVED: To exhibit a high elastic modulus and a high refractive index, excellent adhesion to a plastic substrate and transparency, and a lens layer exhibiting excellent shape holding power over a wide temperature range, and being formed by external force. Provided is an active energy ray-curable resin composition for a Fresnel lens that is less likely to cause chipping or cracking, and a Fresnel lens sheet using the composition. SOLUTION: An epoxy (meth) acrylate (a) having a cyclic structure, an epoxy equivalent of 450 g / eq or more having two or more (meth) acryloyl groups, a specific trifunctional (meth) acrylate (b), and propylene The aliphatic polyhydric alcohol having an oxide structure has a molecular weight of 7 An active energy ray-curable resin composition for a Fresnel lens containing as essential components a (meth) acrylate (c) of not more than 00 and a monofunctional (meth) acrylate (d) having a cyclic structure, and the composition were used. Fresnel lens sheet. |
