Abstract
A sheet-like article () for an absorbent article of the invention includes a plurality of absorbent units (), each including a long base portion () and water-absorbent polymer particles () fixed to a surface of one face of the long base portion (). In the sheet-like article (), the absorbent units () are arranged such that their longitudinal direction is oriented in one direction. Before the water-absorbent polymer particles () absorb a liquid, the water-absorbent polymer particles () are located inward of both lateral side edge portions (), of the long base portion (), that extend along the longitudinal direction. When the water-absorbent polymer particles () absorb a liquid, the water-absorbent polymer particles () swell beyond the lateral side edge portions (), of the long base portion (), that extend along the longitudinal direction, and a position, in the thickness direction, of the long base portion () is varied from the position thereof before absorbing the liquid.
