A glass film manufacturing method
- comprising a cutting step of cutting a glass film with a cutting device while conveying the glass film,
- wherein, in the cutting step, a belt conveyor having a suction portion only at a position corresponding to a center portion of the glass film in a width direction is arranged on an upstream side of the cutting device, and
- wherein, in the cutting step, the glass film is supplied to the cutting device by the belt conveyor while the suction portion sucks only the central portion of the glass film in the width direction so that wrinkles of the glass film in the cutting device are suppressed.
