Abstract
An object of the present invention is to provide a filler-containing resin film in which shedding of inorganic materials or the like is suppressed, a resin composition that can be used in production of the filler-containing resin film, and a method for producing the filler-containing resin film. The filler-containing resin film of the present invention is a filler-containing resin film comprising: a vinylidene fluoride copolymer obtained by copolymerizing vinylidene fluoride and a compound represented by formula (1) (in formula (1), R1, R2, and R3 are each independently hydrogen atoms, chlorine atoms, or alkyl groups having from 1 to 5 carbons; and X′ is an atomic group having a molecular weight of 472 or less and having a main chain configured from 1 to 19 atoms); and an insulating inorganic filler. The resin film is produced by applying onto a substrate and then drying a resin composition containing the vinylidene fluoride copolymer, the insulating inorganic filler, and an organic solvent.
