The present invention relates to a case having a shock absorbing structure for an electronic device which includes a protective shell, a side enclosure frame, and a shock absorbing block. The shock absorbing block is constructed to have a plurality of recesses formed on the side wall of the protective shell such that adjacent recesses are separated by a partition. The recesses are rectangular and the plurality of recesses has a continuous unitary construction along lower part of the four sides of the protective shell. In addition, the side enclosure frame includes an upper protrusion and a lower protrusion, formed on an inner-facing surface of the side enclosure frame. The side wall of the protective shell includes an upper cavity and a lower cavity. The upper protrusion fits within the upper cavity and the lower protrusion fits within the lower cavity.
