Abstract
A nonaqueous electrolyte secondary battery separator film transfer device is provided which realizes a foreign object removing technique that is less likely to cause defects in a separator. The device includes a magnet bar which is arranged in a transfer path and generates a magnetic field for removing, from a separator film being transferred, a magnetic substance adhering to a first surface of the separator film; and an air cylinder which allows a distance to the magnet bar from the first surface of the separator film to be variable.
