Abstract

In an outer covering sheet of an absorbent product, first, second and third adhesive layer elements each extending in a left-right direction are formed on a second covering sheet by spiral spray application. Each of these adhesive layer elements has wide width parts and narrow width parts which are continuous with the wide width parts, respectively. Therefore, hot melt adhesive can be stably discharged across the entire length of the adhesive layer element, unlike in the case where only wide width parts are formed intermittently. As a result, it is possible to obtain the outer covering sheet which is a sheet member having the adhesive layer elements with desired shapes where unevenness is decreased. In the absorbent product which is manufactured with use of the sheet member, the comfort level of the wearer can be prevented from decreasing due to unevenness of thickness of the adhesive layer elements.
