Method of manufacturing cured resin film

Abstract

[Problem] To provide a manufacturing method with which a cured resin film can be manufactured at high yield, and which effectively prevents the occurrence of defects such as wrinkles in the cured resin film. [Solution] Provided is a cured resin film manufacturing method comprising: a first step in which an undried resin film is formed on a support, the undried resin film comprising a heat curable resin composition containing a curable resin and a solvent; a second step in which a curable resin film having a loss of 0.5-7 wt % on heating is formed by drying the undried resin film which has been formed on the support by using a float method to convey the undried resin, which is in the state of having been formed on the support, in a drying device; a third step in which a cured resin film is formed by heat curing the curable resin film; and a fourth step in which the support is detached from the cured resin film.
