Disclosed are a battery cell assembly for a secondary battery, the battery cell assembly for a secondary battery including at least one battery cell; a first frame disposed on one side of the at least one battery cell; and a second frame which is disposed on the other side of the at least one battery cell so as to face the first frame and which is coupled to the first frame so as to protect the edge of the at least one battery cell together with the first frame. The present invention uses a frame type cell support which retains and supports at least one battery cell without separation, thereby providing a battery cell assembly for a secondary battery, namely a sub-battery module receiving body, having improved structural stability and assembly convenience, and a secondary battery including the same.
