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.
