The present invention relates to a super-absorbent resin and a method for preparing the same. In the super-absorbent resin of the present invention, the gel strength index of equation 1 below is 0.5 or more. [Equation 1] Gel strength index = 0.7 psi AUP of super-absorbent resin / CRC of base polymer, wherein, in equation 1, 0.7 psi AUP (g/g) is the value of absorbency under pressure analyzed according to the EDANA WSP242.2.R3, and CRC of the base polymer (g/g) is the value of centrifuge retention capacity obtained by analyzing CRC of the base polymer before surface cross-linking according to the EDANA WSP241.2.R3. |
