    • PROBLEM TO BE SOLVED: To provide a medical pressure-sensitive adhesive composition that, if a medically active ingredient such as a drug is contained, suppresses denaturation etc. caused by its reaction with such the ingredient, has no risk of deteriorating effectiveness of the ingredient and, when used for forming a pressure-sensitive adhesive layer of a medical patch or a patch preparation, exerts high fixability onto skin surface and imparts excellent fixability to a medical tool such as a catheter. SOLUTION: The composition includes an acrylic copolymer obtained by copolymerizing a monomer component containing (a) at least one monomer of alkyl (meth)acrylate and (b) at least one monomer of N-hydroxyalkyl ester (meth)acrylamide, provided that the monomer component is substantially free of a monomer having a carboxyl group.
