PROBLEM TO BE SOLVED: To obtain the subject water absorbent suitable for an absorbable article well-balanced in absorption quantity under no-load, absorption quantity under load, an absorbing speed and gel strength being fundamental characteristics of the absorbent in a high level. SOLUTION: A water absorbent consists of a water absorble resin (A1) wherein the absorption quantity under no-load to a physiological saline soln. is 55 g/g or more and the absorbing speed of the physiological soln. is 40 sec or less and a water absorbable resin (A2) wherein the absorption quantity to the physiological saline soln. under load of 40 g/cm2 is 20 g/g or more and gel elastic modulus is 7,500 N/m2 or more and the resins (A1), (A2) are mixed in a ratio of 3:7-7:3 on a mass basis.
