[Problem] To provide a particulate water-absorbing agent that can significantly reduce re-wet even when pressure is applied to the particulate water-absorbing agent from the outside when the particulate water-absorbing agent is in a swollen state.

[Solution] A particulate water-absorbing agent comprising a surface-crosslinked polyacrylic acid (salt)-based water-absorbing resin as a main component and satisfying the following expression (1).

AAP(2.06 kPa)+RCAP(2.06 kPa)≥0.58×CRC+55.6  (1),

wherein AAP (2.06 kPa) represents absorption capacity (g/g) under a pressure of 2.06 kPa, RCAP (2.06 kPa) represents retention capacity against pressure after swelling (g/g), and CRC represents absorption capacity without pressure (g/g).
