An object thereof according to the present invention is to provide a solid electrolyte with high ion-conductivity which is cheap and exhibits high conductivity even in an alkaline form, and also can stably keep high conductivity because of a small amount of the leak of a compound bearing conductivity even in a wet state; a method for manufacturing the same; and an electrochemical system using the solid electrolyte, such as a fuel cell. The solid electrolyte with high ion-conductivity comprises a hybrid compound which contains at least polyvinyl alcohol and a zirconic acid compound, as constituents, and also contains a nitrogen-containing organic compound having a structure of amine, quaternary ammonium compound and/or imine, obtained by hydrolyzing a zirconium salt or an oxyzirconium salt in a raw material solution in which a solvent including water, polyvinyl alcohol, a zirconium salt or an oxyzirconium salt and a nitrogen-containing organic compound having a structure of amine, quaternary ammonium compound and/or imine coexist, removing a solvent and contacting with alkali.
