Abstract
The present invention provides an easy method for producing a water absorbent agent that has a low moisture content and that has a small dust generation amount without decreasing various physical properties. A present inventive method for producing a water absorbent agent of the present invention includes mixing not lower than 0.06 parts by mass and not higher than 5 parts by mass of an inorganic acid alkali metal salt powder with 100 parts by mass of a water-absorbent resin in an indefinite ground form.
