Provided is a water-absorbing agent that reduces the amount of return in a paper diaper without using expensive raw materials and equipment while maintaining liquid permeability and water absorption speed to some extent. The water-absorbing agent of the present invention is a water-absorbing agent mainly composed of a polyacrylic acid (salt) -based water-absorbing resin, and has a saline flow conductivity (SFC), a crevice water magnification under pressure, and a particle size of 150 μm or more and 710 μm. The proportion of particles that are less than indicates a value within a certain range. |
