Claim:
1. A method for producing an absorbent body for an absorbent article including the absorbent core material containing therein hydrophilic fibers and superabsorbent polymer particles and covered with at least partially liquid-permeable cover sheet, wherein: in a step of forming a first liquid absorbent layer containing the hydrophilic fibers and the superabsorbent polymer particles in a mixed state and a second liquid absorbent layer containing the hydrophilic fibers but none of the superabsorbent polymer particles so that these two liquid absorbent layers overlap with each other on a support running in a machine direction, the hydrophilic fibers are dispersed toward the support within a chamber partially covering the support and the superabsorbent polymer particles are dispersed toward the support from an opening of a dispersing pipe set at least one of inside and outside the chamber wherein a distance dimension between the dispersing pipe set inside the chamber and the support is in a range of 5 to 20 mm and a distance dimension between the dispersing pipe set outside the chamber and the support is in a range of 5 to 100 mm; and the dispersing pipe set outside the chamber is set at least one of upstream and downstream in the machine direction of the chamber.
