The arrangement of electric circuit boards and an optical unit including a CCD is optimized to minimize the volume of the electronic camera, and to shield the circuit boards from one another by utilizing the essential components of the camera themselves. A memory card chamber and an LCD unit are separately shielded with conductive walls. An analog circuit board, a power source circuit board, the memory card chamber, a digital circuit board and the LCD unit are arranged in that order, parallel to one another, and perpendicular to the optical axis of the optical unit. Thus, the digital circuit board that is the worst source of noises can be shielded by the memory card chamber and the LCD unit without any special shielding members, and a signal wire between the CCD and the analog circuit can be perpendicular to the circuit boards. A metal casing of the camera connects to the walls of the memory card chamber and the LCD unit in order to reinforce the ground.
