PROBLEM TO BE SOLVED: To provide a process for producing a flexible substrate exhibiting excellent carrying performance of a flexible substrate material while suppressing damage on the substrate material. SOLUTION: In the process for producing a substrate where substrate materials 4 are carried while coupling the edges thereof in the carrying direction by means of a substrate connection tape 1 produced by laminating at least a layer dissolving into etching liquid, a layer dissolving into resist removing liquid and exhibiting etching resistance, and a layer dissolving into resist removing liquid and exhibiting sensitivity to UV-rays, tape paste side at a tape paste portion and/or the rear surface is irradiated with UV-rays after the substrate connection tape 1 is pasted.
