To provide a friction reducing agent capable of significantly reducing frictional resistance of an aqueous liquid, a coating material containing the friction reducing agent, and a friction reducing method using the friction reducing agent.SOLUTION: There is provided a coating material containing a friction reducing agent comprising a water-soluble polymer compound having an ammonium salt structure in a side chain. The water-soluble polymer compound preferably has a repeating unit represented by the general formula (1). (Ris H or a methyl group; A is O or an NH group; Ris an alkylene group or an arylene group; Rto Rare each independently an alkyl group or an aryl group; and Xis a monovalent anion.)SELECTED DRAWING: None
