PROBLEM TO BE SOLVED: To provide a UV-polymerizable acrylic self-adhesive composition giving high self-adhesion power and high cohesive power by UV-curing; an acrylic self-adhesive using the UV-polymerizable acrylic self-adhesive composition; and a self-adhesive tape or a self-adhesive sheet. SOLUTION: The composition includes a monomer mixture comprising 70-97 wt.% of an acrylic acid and an alkyl ester thereof or a methacrylic acid and an alkyl ester thereof, 15-1 wt.% of an unsaturated carboxylic acid monomer, 15-1 wt.% of a copolymerizable monomer with at least one hydroxy group (100 pts.wt. in total); 2-30 pts.wt. of a tackifier; 0.1-5 pts.wt. of a photopolymerization initiator; and 0.0.1-5 pts.wt. of a crosslinker.
