The invention provides an adhesive composition for optical members, an adhesive film for optical members, and a surface-protective adhesive film, which can prevent the oxidation and color change of an adhesive for optical members, can control the cost even if the additive amount is large, and are good in precipitation resistance. Meanwhile, the surface resistivity of an adhesive layer is reduced, thereby enabling a surface-protective film to be easily peeled off. The adhesive composition contains an acrylic copolymer, a cross-linking agent, and an antioxidant, which all take (methyl) acrylic alkyl ester as the main component. Moreover, the antioxidant contains phenolic compounds, and ionic compounds.
