Problems solved by technology

However, since bodily fluid adheres to the skin surface (top sheet) of the absorbent article after use, the bodily fluid hinders the bonding between the adhesive portion and the top sheet, and the absorbent article may not be rolled up compactly.

Abstract

Provided is an absorbent article comprising an adhesive part on a non-skin-facing side, the article being capable of being kept in a rolled-up state after use, and of reducing uncomfortable or unpleasant sensations during use. An absorbent article (10) comprises a front-back direction (L), a widthwise direction (W) orthogonal to the front-back direction (L), a rear surface sheet (22) facing a sideopposite a wearer's skin, and an adhesive part (70) provided on a non-skin-facing side of the rear surface sheet (22). The absorbent article (10) further comprises a tape member (60) disposed on thenon-skin-facing side of the rear surface sheet (22) and to the inside of the outer edge of the absorbent article (10). The tape member (60) is configured so as to be capable of extending beyond the outer edge of the absorbent article (10).

Description

technical field [0001] The present invention relates to an absorbent article having, on the back sheet side, an adhesive portion for fixing to clothing, such as a sanitary napkin, a panty liner, a breast pad, an incontinence pad for adults, a stool pad, or a sweat-absorbing sheet. Background technique [0002] Absorbent articles such as sanitary napkins and pantiliners are attached to the inside of wearing articles worn by wearers during use. Generally, an absorbent article attached to the inner side of a wearing article has an adhesive portion for preventing the absorbent article from shifting relative to the wearing article. The adhesive portion is provided on the surface of the absorbent article opposite to the skin side (the side facing the wearer's skin). In such an absorbent article, if the absorbent article detached from the wearing article is rolled up in the longitudinal direction after use, the adhesive portion will come into contact with the skin surface of the a...
