PROBLEM TO BE SOLVED: To provide a substrate-less double-sided adhesive layer where the occurrence of parting is suppressed.SOLUTION: There is provided a long laminate 10 comprising: a light release sheet 1; an adhesive layer 2; and a heavy release sheet 3, where a release surface of the light release sheet is in contact with one principal surface of the adhesive layer 2, and the heavy release sheet is in contact with the other principal surface. The heavy release sheet comprises at least two separable portion sheets capable of being separated from each other, formed by at least one slit S1 cutting the principal surface of the heavy release sheet in a longitudinal direction. One of the separable portion sheets is a first end surface-containing portion sheet 31 which contains one (3B) of the end surfaces in a width direction of the heavy release sheet 3; a length (L1) in the width direction of the first end surface-containing portion sheet 31 is shorter than a length (L2) in the width direction of the whole separable portion sheets other than the first end surface-containing portion sheet 31; and the slit S1 forming the first end surface-containing portion sheet 31 cuts the heavy release sheet 3 as well as the adhesive layer 2. |
