PROBLEM TO BE SOLVED: To provide a plaster having excellent stability of ascorbic acids, scarcely causing a residue of an ointment when used, nor a sticky feeling, having good plastering properties, and producing a good bleaching effect and an effect of making the skin sound. SOLUTION: This plaster is so formed that an ointment layer is applied to at least one of surfaces of a substrate, wherein the ointment layer comprises a pressure-sensitive adhesive, the ascorbic acids, and a modifier, and the pressure-sensitive adhesive is obtained by polymerizing at least one kind of monomer selected from the group consisting of (meth)acrylic acid and an (meth)acrylic acid ester.
