Electrolytic solution contains non-aqueous solvent and electrolyte salt dissolved in the non-aqueous solvent. The non-aqueous solvent contains a first compound, and the first compound is at least one type selected from a group including 1,3-diethyl-4-methyl-1-cyclobutene and a fluoro-substituted compound of the 1,3-diethyl-4-methyl-1-cyclobutene. An electricity storage element is configured using this electrolytic solution.
