PURPOSE: A cellular phone is provided to detachably install a battery on one side of a body, and to enable the battery to mount a camera module thereon, thereby using a camera regardless of whether a folder is open/shut and enabling a user to selectively buy a camera only. CONSTITUTION: When a user operates a functional key(110) of a body(100), a processor(500) applies a current flowing into the body(100) from a battery(300) to a power terminal and a ground terminal of a connection terminal(310), and supplies power to a camera module(400). When the user operates the functional key(110) to control an operation of a camera(410), the processor(500) applies a driving signal to the camera module(400) through a data input terminal, and takes a picture by the camera(410). If the user takes the picture as watching an internal display window(210) opposite to the camera(410), an image is displayed on the internal display window(210). If the user takes a self picture as watching the camera(410), an image is displayed on an external display window(220).
