PROBLEM TO BE SOLVED: To provide a water absorbent for use in preparing a water-absorbent article capable of showing a high absorption capacity (absorption amount and absorption rate) and suppressing gel-blocking and water leakage in any situation (regardless of a posture of a wearer such as a sitting posture or a lying posture). SOLUTION: The water absorbent comprises a mixture of 100 parts per weight of water-absorbent resin particles (A) and 0.01 to 1 parts per weight of thermally bondable resin particles (B) having a softening temperature of 50 to 180°C. It is preferable that the water absorbent satisfies the formulae (1) to (4), wherein (X) represents the amount of water (g/g) retained in the absorbent after one hour of immersion in physiological saline solution, (Y) represents the flow rate (ml/min) of physiological saline solution passing through the absorbent under a load of 2 kPa after one hour of immersion in physiological saline solution, and (Z) represents the amount of water (g/g) absorbed after one minute of contact with physiological saline solution.
