Abstract: Aiming at improvement in the life and rate characteristic of the secondary battery, the semisolid electrolytic solution, the semisolid electrolyte layer, the electrode, and the secondary battery are provided. The semisolid electrolytic solution contains a solvation electrolyte salt, an ethereal solvent for forming a solvation ion liquid together with the solvation electrolyte salt, and a low-viscosity solvent. The mixture molar ratio of the ethereal solvent to the solvation electrolyte salt is in the range from ≥0.5 to ≤1.5. The mixture molar ratio of the low-viscosity solvent to the solvation electrolyte salt is in the range from ≥4 to ≤16.
