A mold release film for LED production, which is obtained by laminating a coating layer on a multilayer film, and which is characterized in that: the multilayer film has polybutylene terephthalate resin layers (layers A) serving as both outer layers and a polyester elastomer layer (layer B) serving as an inner layer; the coating layer is laminated on at least one of the layers A, which are arranged as both outer layers of the multilayer film, and contains a reaction product that is obtained from 100 parts by mass of a fluorine-containing copolymer (C) and 5-25 parts by mass of a crosslinking agent (D) having 2 or more isocyanate groups; the fluorine-containing copolymer (C) is configured from a fluoroolefin, a cyclohexyl group-containing acrylate and a hydroxyl group-containing vinyl ether; and the coating thickness is 0.1-0.3 μm. |
