To provide a camera which can be reduced in space for a battery, so as to be made light in weight and small in size by integrating a cartridge controlling the size of the camera and the battery.

Positive and negative contacts 8 and 9 can be taken out from the side surface of a frame. The positive and negative contacts 8 and 9 are electrically connected to a camera main body, to make the drive of a camera system possible. Further, the cartridge 12 is provided in the camera main body 11 and a film is fed from the cartridge 12. At this time, a sheet-like battery is wound on the outer peripheral part of the cartridge 12, to be used as an outside case. The positive and negative contacts 8 and 9 are exposed on the top surface and connected to the connecting terminals 14 and 15 of the main body 11 respectively. Thus, the cartridge 12 for fixing the thickness of the camera is integrally provided with the function of the battery, so that the camera can be made small in size and light in weight by the unification of the function.
