PROBLEM TO BE SOLVED: To provide a water-absorbing resin suitable for use in an absorber and an absorbent article which permit the thickness to be reduced without causing a problem in an actual use condition.
SOLUTION: The water-absorbing resin 9 shows a pressure absorption quantity of 10 g/g or below of artificial urine 30 seconds later from the start of absorption and shows a pressure absorption quantity of 20 g/g or above of the artificial urine 30 minutes later from the start of absorption. The water-absorbing resin 9 is combined with hydrophilic fibers to make the absorber. In the absorber, the water-absorbing resin 9 accounts for 30 wt.% or higher and lower than 100 wt.% of the total weight of the absorber. The absorber forms an absorbent article by being held between a liquid-permeable sheet and a liquid-impermeable sheet. The water-absorbing resin 9 is finished hydrophobic and preferably be given surface bridging in addition to the finish.
