PROBLEM TO BE SOLVED: To provide an absorber excellent in diffusion of liquid and minimized in flowback quantity, and an absorptive article using it. SOLUTION: This absorber comprises a water absorptive resin in which the absorptive swelling pressure after 10 seconds from water absorption start is 10,000 Pa or less in a measurement of absorptive swelling pressure by use of physiological saline (0.9 wt.% sodium chloride aqueous solution) as test solution, and the absorptive swelling pressure after 300 seconds from water absorption start is 80,000 Pa or more, and a hydrophilic fiber. The water absorptive resin is subjected to surface crosslinking, and further preferably subjected to hydrophobic treatment. This absorber contains 30 wt.% or more and less than 100 wt.% of the water absorptive resin in relation to the total weight. The absorber is retained between a liquid permeable sheet and a liquid impermeable sheet to constitute the absorptive article. |
