Abstract: Water-absorbing resin particles have a repulsion rate of 5% or more according to the formula (h3?h2)/h1×100(%) when a cylinder with an inner diameter of 25.4 mm, which has a mesh-like bottom onto which 0.2 g of the water-absorbing resin particles are sprinkled, is placed in a container having ion exchange water in an amount of 30 times a mass of the water-absorbing resin particles, where h1 represents a free swelling height (mm) of the water-absorbing resin particles after 1 minute from initiation of water absorption, h2 represents a height (mm) of the water-absorbing resin particles after a load of 1.3×103 Pa is applied to the water-absorbing resin particles for 1 minute after 1 minute from initiation of the water absorption, and h3 represents a height (mm) of the water-absorbing resin particles after 1 minute from release of the load applied when measuring h2.
