PROBLEM TO BE SOLVED: To provide an adhesive layer for electric insulation, which has a low dielectric constant, excellent insulation performance and turbidity prevention performance at high temperature and high humidity, while the adhesive layer comprising an adhesive composition containing only an acrylic monomer having a general structure as a main component, and to provide an adhesive film for electric insulation, and an optical member to which the adhesive film is adhered.SOLUTION: An adhesive layer for electric insulation is obtained by crosslinking an adhesive composition comprising the following acrylic copolymer and a crosslinking agent. The acrylic copolymer is prepared by copolymerizing 4 to 60 parts by weight in total of vinyl monomers having one or more polyalkylene oxide chains, 95.5 to 25 parts by weight in total of alkyl (meth)acrylate having an alkyl group having 1 to 14 carbon atoms, and 0.5 to 15 parts by weight in total of copolymerizable vinyl monomers having at least one functional group of a hydroxyl group and a carboxyl group, where the total of all monomers is set to 100 parts by weight. |
