Abstract: The present invention relates to a super absorbent polymer. The super absorbent polymer contains polymer particles formed of large pores in a certain amount or more, and thus can exhibit large surface area and excellent initial absorption capacity. Therefore, when the super absorbent polymer is used, it can provide a sanitary material such as a diaper or a sanitary napkin which can quickly absorb body fluids and impart a dry and soft touch feeling.
