4 Claims

1. A method of producing a fluororesin cured product, comprising:

baking a photosensitive resin composition at a temperature of 140° C. or lower for curing to form a fluororesin cured product, wherein the photosensitive resin composition comprises:

a fluororesin having a crosslinking site;

a solvent; and

a photopolymerization initiator,

wherein the fluororesin contains a repeating unit derived from a hydrocarbon having a fluorine atom, and

wherein the repeating unit derived from a hydrocarbon having a fluorine atom has a structure represented by the following formula (1-1);

wherein each Rf independently represents a fluorine atom or a perfluoroalkyl group selected from a C1-C6 linear, C3-C6 branched, or C3-C6 cyclic perfluoroalkyl group; and R^1-2represents a hydrogen atom or an alkyl group selected from a C1-C6 linear, C3-C6 branched, or C3-C6 cyclic alkyl group.
