PURPOSE: An exposing apparatus of a flexible circuit board is provided to increase exposure speed, improve productivity, reduce size, simplify structure, and make exposure quality uniform over the entire area. CONSTITUTION: An exposing apparatus of a flexible circuit board comprises a drum(11), two board attaching press rollers(25a,25b) and a drum separation avoid pressing roller(25c). The board attaching press rollers(25a,25b) are arranged at the bottom of the drum(11) for pressing and attaching an exposure area of an FPC board(17) to a photo mask on the surface of the drum(11). The drum separation avoid pressing roller(25c) is arranged at the top of the drum(11) for pushing the drum downward to avoid separation of the drum(11) whatever the diameter of the drum(11) is. The rollers(25a,25b,25c) fix the drum(11) by pressing the drum(11) toward the drum center axis and attach the FPC board(17), simultaneously.
