PURPOSE:The titled tape, containing a specific chemical and an organic acid salt or inorganic acid salt of Mg, Ca, Zn or Al in a pressure-sensitive adhesive layer provided on a base material, capable of dissolving a large amount of the chemical therein without deterioration thereof, and having stable dissolution state with time. CONSTITUTION:A remedial adhesive tape containing a hydrophilic chemical, e.g. a nonsteroid anti-inflammatory agent such as ''Indomethacin'' or ''Diclofenac'', having carboxyl groups or alkali metal salts thereof in the molecule thereof, and slightly soluble or insoluble in an ester (1g or less amount of dissolved chemical in 100g ester such as ethyl acetate at 20 deg.C and 10-100wt%, based on the amount of the chemical, organic acid or inorganic acid salt of a metal selected from Mg, Ca, Zn or Al, in a pressure-sensitive adhesive layer, preferably a pressure-sensitive adhesive layer containing an alkyl acrylate or methacrylate as a polymerization component, provided in a base material. EFFECT:A high chemical effect can be obtained since a large amount of the chemical can be contained.
