PROBLEM TO BE SOLVED: To reduce the thickness of a microlens array using high and low refractive index resin layers each comprising an ultraviolet-curing resin. SOLUTION: The objective microlens array comprises a laminated body of a high refractive index resin layer and a low refractive index resin layer. The low refractive index resin layer has a refractive index of <=1.40 and is obtained by the ultraviolet curing of a composition comprising (1) a (meth) acrylate derivative which is a polymer having a perfluoropolyoxyalkylene as the principal chain structure, both ends of which have a (meth)acryloyloxy group by way of a fluoro(oxy)alkylene group which may have a hydroxyl group as a substituent, and (2) a fluorine-containing (meth)acrylate monomer.
