Abstract: Provided is a production method for a film laminate by which a tough film can be bonded to a brittle film while the breakage of the brittle film is prevented. The production method for a film laminate of the present invention includes bonding a tough film having an elongated shape to a brittle film having an elongated shape while conveying the brittle film, wherein the method includes bonding the tough film and the brittle film to each other by bringing the tough film close to the brittle film, followed by blowing of a gas from a side of the tough film opposite to the brittle film.

Abstract: Provided is a glass film in which an optical defect is less likely to occur and which has excellent handleability. The glass film has a thickness of 150 μm or less and has flexibility. On one surface of the glass film, the number of deposited contaminants of 5 μm or more is 130/m2 or more, and the number of deposited contaminants of 100 μm or more is 10/m2 or less. On one surface of the glass film, the number of deposited contaminants of 5 μm or more and less than 100 μm is preferably 130 to 1200/m2. The glass film preferably has a length of 100 m or more.
