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 () that are fixed to a surface of first side of the long base portion (). In the sheet-like article (), the absorbent units () are arranged such that the longitudinal direction thereof is oriented in one 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 each long base portion is varied from the position thereof before absorbing the liquid.
