  "textContent": "An objective is to provide a vinylidene fluoride polymer composition that is difficult to swell and dissolve in N-methyl-2-pyrrolidone and can form an electrode with a smooth surface. The vinylidene fluoride polymer composition contains a vinylidene fluoride polymer with a melting point of 130°C or higher. When the vinylidene fluoride polymer composition and N-methyl-2-pyrrolidone are mixed to prepare a vinylidene fluoride polymer dispersion with a content of the vinylidene fluoride polymer of 6 mass%, a ratio of a viscosity of the vinylidene fluoride polymer dispersion at 30°C to a viscosity of N-methyl-2-pyrrolidone at 30°C is 20 or less, and when the vinylidene fluoride polymer dispersion is stirred and then allowed to stand for 15 minutes, a rate of change in content of the vinylidene fluoride polymer in an upper 40 volume% area of the vinylidene fluoride polymer dispersion before and after the standing is 2 mass% or less.",
