PROBLEM TO BE SOLVED: To eliminate the need of a gap for soldering and to make a film unit with a lens thinner in thickness by providing a printed circuit board with an electrically conductive pattern only on its one surface and making the conductive pattern face to a unit main body. ;SOLUTION: The printed circuit board 4 is arranged in contact with the external wall of a roll film chamber 1b. The board 4 is provided with the conductive pattern only on its surface on the side of the unit main body 1, and various electric parts for a stroboscopic circuit are arranged in space 5 formed by the external wall of a photographing part 1a, the external wall of the chamber 1b and the board 4 and space 6 formed by the external wall of the chamber 1b, the external wall of a battery chamber 1c and the board 4, and then soldered. Therefore, since they are not soldered on the surface of the board 4 on the side of a front cover 2, the cover 2 is arranged only by making the back surface of the cover 2 abut on the board 4 or forming a small gap, and the film unit with a lens is thinned nearly by the length equivalent to the height of soldering.;COPYRIGHT: (C)1999,JPO
