Abstract This gel electrolyte comprises a vinylidene fluoride polymer and a nonaqueous electrolyte. The vinylidene fluoride polymer comprises a first vinylidene fluoride polymer and a second vinylidene fluoride polymer. The first vinylidene fluoride polymer gels in an inverted gelation measurement after cooling, to 25°C, a solution that is dissolved in a propylene carbonate/dimethyl carbonate (1/1 mass ratio) solvent so that the concentration is 10 mass%, and the second vinylidene fluoride polymer does not gel in the gelation measurement. Cet électrolyte en gel comprend un polymère de fluorure de vinylidène et un électrolyte non aqueux. Le polymère de fluorure de vinylidène comprend un premier polymère de fluorure de vinylidène et un second polymère de fluorure de vinylidène. Le premier polymère de fluorure de vinylidène se gélifie dans une mesure de gélification inversée après refroidissement, à 25°C, d'une solution qui est dissoute dans un solvant de carbonate de propylène/carbonate de diméthyle (rapport massique de 1/1) de sorte que la concentration soit de 10% en masse, et le second polymère de fluorure de vinylidène ne se gélifie pas dans la mesure de gélification. 本発明のゲル状電解質は、フッ化ビニリデン重合体と、非水電解液とを含む。フッ化ビニリデン重合体は、第1フッ化ビニリデン重合体と、第2フッ化ビニリデン重合体とを含む。第1フッ化ビニリデン重合体は、プロピレンカーボネート/ジメチルカーボネート(1/1質量比)溶媒に、濃度が10質量%となるように溶解させた溶液を25℃に冷却した後の倒置法によるゲル化測定において、ゲル化するものであり、第2フッ化ビニリデン重合体は、前記ゲル化測定において、ゲル化しないものである。
