Provided is an absorbent body that, for example, in a case where the absorbent body has been used in an absorbent article, such as a thin disposable diaper, having an absorbent body with a low proportion of fiber material (hydrophilic fibers) such as pulp, enables the absorbent article such as a disposable diaper to have an improved liquid trapping function on second and subsequent urinations over the conventional ones and particularly to have an increased amount of liquid trapped under load on the second and subsequent urinations over the conventional ones. Also provided is a water-absorbing resin that is used in the absorbent body and has an increased absorption capacity under load on the second and subsequent urinations over the conventional ones.

The absorbent body includes a water-absorbing resin having a gel expansion force under a load of 4.83 kPa of 26 N or more.
