Disclosed herein is a chip on board lead package for optical mice and lens cover for the same. A semiconductor chip on board package for optical mice has a board, a semiconductor chip, at least one circuit pattern, at least one bonding wire, and a lens cover. The board has top and bottom surfaces, and a pair of via holes. The semiconductor chip is attached to a center portion on the top surface of the board and provided with a plurality of electrode terminals. The circuit pattern is formed on the top surface of the board. The bonding wire electrically connects the electrode terminals of the semiconductor chip with the circuit pattern. The lens cover encloses the top surface of the board and has a lens disposed on the same axis as that of the semiconductor chip, a plurality of electrode pins formed at positions of the lens cover corresponding to the positions of the via holes in the board to be integrated with the lens cover, and an opening formed in a center portion within the lens cover.
