LAMINATED FILM MANUFACTURING METHOD, CIRCUIT BOARD MANUFACTURING METHOD, ROLL BODY, AND RELEASE FILM

摘要

PROBLEM TO BE SOLVED: To provide a laminated film manufacturing method capable of suppressing the occurrence of a temperature variation when heating a laminated film in a wound state.SOLUTION: A laminated film manufacturing method comprises: a preparation step of preparing a laminated film comprising a substrate film and a transparent conductive film installed on the substrate film; a winding step of winding the laminated film; and a heat treatment step of heating the laminated film in a wound state. In the winding step, a release film having a release surface is inserted between the laminated films superposed to each other by the winding. A plurality of thermal conductive fillers are dispersed in the release film.SELECTED DRAWING: Figure 1
