Disclosed is a solid polymer electrolyte which has a water cluster structure formed by a hydrophilic group and occluded water in the solid polymer electrolyte, and which has a "water cluster structure difference" of 15.4 x 0.072 nm or less, wherein the "water cluster structure difference" is a difference between the diameter of a pore in the water cluster structure and the diameter of a bottleneck part in the water cluster structure both calculated by a dissipative particle dynamics method. The solid polymer electrolyte has improved ionic conductivity. L'invention concerne un électrolyte polymère solide qui a une structure à agrégat aqueux formée par un groupe hydrophile et de l'eau obstruée dans l'électrolyte polymère solide, et qui a une = différence de structure d'agrégat aqueux = de 15,4 x 0,072 nm ou moins, la = différence de structure d'agrégat aqueux = étant une différence entre le diamètre d'une pore dans la structure d'agrégat aqueux et le diamètre d'une partie de col dans la structure d'agrégat aqueux, tous deux calculés par un procédé de dynamique dissipatif des particules. L'électrolyte polymère solide a une connectivité ionique améliorée.
