Abstract
A flow of an excretion liquid into a side pocket is accomplished with a simple structure using an imperforated sheet. A side pocket extending in a front-back direction LD is disposed in an absorbent article on a lateral side of an absorber. The side pocket is surrounded by a side cover portion reaching the back surface side of the absorber from above a side of a top sheet via an upper portion, an outer side, and a lower portion of the side pocket. A portion located above the side of the top sheet in the side cover portion includes a non-bonded portion not bonded to the top sheet and a bonded portion located on both front and back sides of the non-bonded portion. A gap between the side cover portion and the top sheet in the non-bonded portion is open above the top sheet and toward the side pocket.

- a top sheet covering a front surface side of the absorber;
- a liquid impervious sheet covering a back surface side of the absorber;
- and
- rising gathers rising from both sides of the top sheet, wherein a side pocket extending in a front-back direction is disposed on a lateral side of the absorber,
- wherein the side pocket is surrounded by a side cover portion formed of a sheet material reaching a back surface side of the absorber continuously from above a side of the top sheet via an upper portion, an outer side, and a lower portion of the side pocket,
- wherein a portion of the side cover portion located above the side of the top sheet includes a non-bonded portion not bonded to the top sheet and a bonded portion located on both front and back sides of the non-bonded portion,
- wherein a gap between the side cover portion and the top sheet in the non-bonded portion is open above the top sheet and toward the side pocket,
- wherein the sheet material further includes a protruding portion protruding from the non-bonded portion and the bonded portion, and the protruding portion forms the rising gather,
- wherein an elongated side cover elastic member is disposed in the front-back direction at least outside a portion located above the side pocket in a width direction in the side cover portion, and
