1. A glass film-resin composite comprising:
a glass film, and
a resin tape laminated to at least one surface of the glass film through an adhesive, wherein
the width 1 (mm) of the resin tape satisfies the following formula (1);

OG Complex Work Unit Math
(where: 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 glass film is a glass ribbon,
wherein a plurality of the resin tapes are laminated such that the plurality of the resin tapes are provided in the vicinity of each of width-directional opposite edges of the glass ribbon, in spaced-apart relation to each other,
wherein each of the resin tapes has a width of 1% to less than 5% the width of the glass film,
wherein each of the resin tapes has a width of less than 5 mm, and
wherein the resin tape is laminated to the at least one surface of the glass film through an adhesive having no peelability.
