Disclosed is a composition for a lithium secondary battery electrode, which is excellent in dispersibility and adhesion of an active material, capable of maintaining a suitable viscosity for a long period of time, and capable of producing a high capacity lithium secondary battery even when the amount of the binder is small. The purpose is to provide. The present invention relates to a composition for a lithium secondary battery electrode comprising an active material, a polyvinyl acetal resin and an organic solvent, wherein the polyvinyl acetal resin comprises a structural unit having a hydroxyl group represented by the following formula (1) (1), and a structural unit having a carboxyl group and containing a structural unit having a hydroxyl group represented by the formula (1) (wherein, in the formula , And R 1 represents a hydrogen atom or an alkyl group having 1 to 20 carbon atoms.
