Abstract: Provided is a glass film-resin composite body which makes it possible to obtain a long-length (e.g., 500 m or more-long) glass roll. The glass roll with resin film comprises a glass film, and a resin film laminated to at least one surface of the glass film through an adhesive, wherein a creep amount a of the adhesive is 50 μm or less, as measured after applying a tensile shear load per unit area of the adhesive of 5 g/mm2, to the resin film for 48 hours, in a state in which the glass film is fixed in 23° C. and 50% RH.

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.
