Abstract
Provided are a water-absorbing resin having more excellent balance of fluid retention capacity, liquid permeability, and low dustiness and a novel measurement method which enables evaluation of excellent physical properties of the water-absorbing resin. A method for measuring an absorption speed of a particulate water-absorbing agent is a method including the step of applying pressure to a portion of a bottom surface of a measurement container () by use of a flat plate () in a state in which part or whole of the particulate water-absorbing agent () is fixed on the bottom surface of the measurement container (), the bottom surface being surrounded by a frame, introducing an aqueous solution through a liquid injection inlet () with which the flat plate () is equipped, and then measuring the amount of time elapsed until an end of absorption of the introduced aqueous solution by the particulate water-absorbing agent ().
