PROBLEM TO BE SOLVED: To provide an apparatus for bagging a culture medium, capable of charging a bag with the culture medium while forming a film taken out from an original roll in a roll shape into a cylindrical shape to bag the culture medium, and capable of attaching a filter for ventilating the air in the interior or exterior to the film while adjusting the position thereof. SOLUTION: The film S is cylindrically heat-sealed to provide a bag, and the culture medium B is bagged in the bag P. The film S is nipped and held in the middle of the conveying passage between a film-mounting part 2 and a former 3 for folding the film S into a cylindrical shape, and an open hole H is formed by a punching structure 16 at a prescribed position, A filter F is positioned at the open hole H formed in the film, and attached to the film S by a welding structure 34 to attach the filter F for ventilating the interior or exterior air at the position of the open hole H of the film S while readily carrying out the positioning. The film S having flexibility is nipped and held by an upper and lower nipping plates 17 and 23 installed in the punching structure and the opening hole H is formed by a cutter blade 18 in the film S.
