Glass film-resin composite

A glass film-resin composite comprising:

• a glass film having a first surface and a second surface opposite the first surface;
• and
• a resin tape laminated to the first surface of the glass film through an adhesive, wherein
• the second surface of the glass film is free from having the resin tape, and
• the width l (mm) of the resin tape satisfies the following formula (1);
• l

• a represents a reinforcement coefficient (mm*(μm)1/2) which is 1.10 or more;
• Eg represents the Young's modulus (GPa) of the glass film;
• Ep represents the Young's modulus (GPa) of the resin tape;
• tg represents the thickness (μm) of the glass film;
• and tp represents the thickness (μm) of the resin tape),
• wherein
• the resin tape has a width of 2.5% to less than 5% the width of the glass film, and
• the thickness tg of the glass film is 200 μm or less.
