The present invention provides a nip apparatus and a nip method which reduce consumption of gas used without scratches which are produced when a material to be treated (such as a band-shaped film and the like) is pressed against a support (such as a roll and the like). The invention is characterized in that a gas storage chamber, which stores gas with a pressure higher than outside atmospheric pressure, is disposed at a position facing a film, and the film is conveyed while being pressed against a roll with a reduced consumption of gas.
