The present invention relates to a super absorbent polymer having more improved absorbency under pressure and liquid permeability, and a method for producing the same. The super absorbent polymer comprises a base polymer powder including a cross-linked polymer of a monomer containing a water-soluble ethylenically unsaturated compound or its salt; and a surface cross-linked layer that is formed on the base polymer powder and is further cross-linked from the cross-linked polymer, wherein a glass hollow particle having a micron-scale particle size is included on the surface cross-linked layer.
