PROBLEM TO BE SOLVED: To provide: a double-sided tacky sheet capable, when coiled and stored in the form of a roll, of preventing the generation of multiple fine valleys and peaks on the tackifier layer surface; and a coiled body obtained by coiling the double-sided tacky sheet.SOLUTION: The double-sided tacky sheet of the present invention includes a tackifier layer, a first release film, and a second release film, the peel force of the second release film from the tackifier layer is less than the peel force of the first release film from the tackifier layer, the tackifier layer is formed by using a tackifier including an active energy ray-curable resin, the gel content of the tackifier layer immediately after the formation thereof is at least 70%, in a case where the gel content of the tackifier layer immediately after the formation thereof is defined as X [%] and where the gel content of the tackifier layer seven days after the formation of the tackifier layer is defined as Y [%], the relation of X/Y≥0.9 is satisfied, and the ratio occupied, on first and second surfaces of the tackifier layer, by valleys and peaks beyond a range of ±200 nm from the reference plane is 20% or less. |
