摘要: An issue to be solved is to provide a vinylidene fluoride copolymer composition having stable dispersibility in a dispersion medium over a long period of time. The vinylidene fluoride copolymer composition that solves the above issue contains comprising a vinylidene fluoride copolymer, the vinylidene fluoride copolymer comprising a structural unit derived from vinylidene fluoride and a structural unit derived from a fluorinated alkyl vinyl compound, wherein the vinylidene fluoride copolymer composition has a melting point of 140°C or lower, when a reversing heat flow of the vinylidene fluoride copolymer composition is measured with a temperature-modulated differential scanning calorimetry, the vinylidene fluoride copolymer composition has endothermic peaks having an amount of enthalpy of fusion (ΔHm) of 2J/g or more with two or more peak tops, and, an absolute value of a difference between a peak top temperature of a largest endothermic peak among the endothermic peaks and the melting point of the vinylidene fluoride copolymer composition is 10°C or lower, and after a dispersion comprising butyl butyrate and the vinylidene fluoride copolymer composition and having a content rate of the vinylidene fluoride copolymer composition of 10 mass% is stirred at 25°C for 30 minutes and left to stand for 20 hours, a content rate of the vinylidene fluoride copolymer composition in an upper 20 vol% of the dispersion is 7.0 mass% or more and 10 mass% or less.
