Summary: | The purpose of the present invention is to provide: an adhesive composition that, without requiring curing for forming an adhesive layer, has a satisfactorily high adhesive strength before ultraviolent irradiation, a satisfactorily large range of decline in the adhesive strength due to ultraviolent irradiation, sufficiently little adhesive residue, and excellent protrusion-inhibiting properties; an adhesive sheet using the adhesive composition; and a manufacturing method for the adhesive sheet. This adhesive composition contains a photopolymerization initiator and a polymer having a methyl acrylate-derived structural unit, a group containing a polymerizable carbon-carbon double bond, and a urethane group, wherein the proportional content of the structural unit is 1 mass% to 60 mass% relative to all structural units constituting the polymer, the content of urethane groups in the polymer is 0.5 mass% to 2.5 mass%, the gel fraction of the polymer is at least 5 mass%, and the adhesive composition essentially does |
