PROBLEM TO BE SOLVED: To provide an electrolyte cell using gel state polymer as the electrolyte, that may improve conservation properties in a high temperature. SOLUTION: In a polymer electrolyte cell having a positive electrode 20, a negative electrode 30, and a gel state polymer electrolyte 40 with lithium salt including LiPF6 and solvent contained in a polymer matrix, characterized in that the polymer matrix is at least a kind of polymerizable monomer polymer selected from polyalkylenglycolacrylate, polyalkyleneglycolmetacrylate, and dielectric substance thereof, wherein assuming that (m) is the number of sum of acrylate group and metacrylate group in one molecule of the polymerizable monomer, and (n) is the number of repetition times of the polyalkyleneoxide in one molecule of the polymerizable monomer, (m) and (n) is determined to satisfy the following conditions: at 1<=m<=2, n<=5; and at 3<=m, n<=5m-5. |
