A secondary battery has a positive electrode, an electrolyte, and a negative electrode. The electrolyte is made up of a high molecular gel electrolyte comprising a matrix polymer and an electrolyte solution included in the matrix polymer. The electrolyte solution is formed by dissolving an ionic compound in a nonaqueous organic solvent. The matrix polymer forms a high molecular network by dispersing (i) a compound containing at least two polymerizable functional groups, (ii) compound having a polymerizable functional group and containing one of a carbonyl group, an amido group, and an oxyalkylene group, and (iii) a vinylidene fluoride polymer and polymerizing them.
