PROBLEM TO BE SOLVED: To obtain a sheet member having an adhesive layer with little unevenness.SOLUTION: In an outer packaging sheet of an absorbent article, a first adhesive layer 45, a second adhesive layer 46, and a third adhesive layer 47 each extending in a lateral direction are formed by spiral spray coating on a second outer packaging sheet 42. The first adhesive layer 45, the second adhesive layer 46, and the third adhesive layer 47 are provided with wide width parts 451, 461, 471, and narrow width parts 452, 462, 472, respectively in a continuous manner. Widths of the respective adhesive layers are gradually changed between the wide width part and the narrow width part. Consequently, a hot melt adhesive can be stably discharged across the entire length of each adhesive layer in contrast with a case where only wide width parts are intermittently formed. Therefore, the outer packaging sheet which is a sheet member having the adhesive layers of a desired shape where the unevenness is reduced can be obtained. In addition, in the absorbent article manufactured by using the sheet member, a decrease in a comfort level of wearing due to the unevenness of a thickness or the like of the adhesive layers can be prevented. |
