摘要：
The invention clarifies absorption properties of a water-absorbent resin as needed in the case where the ratio by weight of the water-absorbent resin to the total of the water-absorbent resin and the fibrous material is ".alpha.," and further the invention provides an absorbent article using a water-absorbent resin which is optimal to the ratio by weight ".alpha." of the water-absorbent resin. A water-absorbent resin, having a concentration absorption index of 35 or more as shown by the following equation (1):A(1-.alpha.)+B.alpha. (1)wherein A (g/g) is an absorption capacity of the resin under no load, andB (g/g) is an absorption capacity of the resin under a load, is used as the water-absorbent resin as used for the absorbent article of at least 0.4 in the ratio by weight ".alpha." of the water-absorbent resin to the total of the water-absorbent resin and the fibrous material.
