A solid battery consisting of a positive electrode, a negative electrode and a separator disposed between the positive electrode and negative electrode wherein at least one of the positive electrode, the negative electrode and the separator comprises a solid electrolyte obtained by dissolving a tetrafunctional polymer compound and an electrolyte salt in a solvent and crosslinking the solution by the irradiation of an actinic radiation and/or by heating, which solid electrolyte comprises a tetrafunctional terminal acryloyl-modified alkylene oxide polymer having a polymer chain represented by following formula (I) as the tetrafunctional polymer compound, and the solvent at a ratio of from 220 to 1,900% by weight to the tetrafunctional polymer compound: wherein R is a residue of an active hydrogen compound selected from the group consisting of diglycerol, pentaerythritol, methylglucoside and ethylenediamine, R1 and R2 each represents a hydrogen atom or a lower alkyl group; R3 represents a hydrogen atom or a methyl group; m and n each represents 0 or an integer of at least 1; in one high-molecular chain, m + n .gtoreq. 35. The solid battery has a high performance and a high- energy density, prevents the occurrence of liquid leakage and gas spouting, and has an excellent mechanical strength. |
