PURPOSE: A focus variable type mobility lens is provided to form a single automatic focus lens by using volume change of index liquid which is transformed by a motion of a drive transparency electromagnet film. CONSTITUTION: A focus variable type mobility lens is formed on the upper side of an image sensor(110). The focus variable type mobility lens comprises electricity variable type mobility index liquid(102a). Activating transparency electromagnet glass(101b) comprises a thin film type electromagnet coil. A drive thin film type transparency electromagnet coil film is moved with magnetic force induced by the thin film type electromagnet coil. The mobility index liquid is transformed by a motion of the drive thin film type transparency electromagnet coil film.
