PROBLEM TO BE SOLVED: To provide a new electrolyte component with high ion conductivity and ion transference, and to provide a nonaqueous secondary cell with excellent durability. SOLUTION: The electrolyte component contains at least one compound out of the compounds expressed by the formulas (1)-(3), and a salt of metal ion belonging to Ia or IIa group of the periodic table, In the formulas, Q represents a group of atoms capable of forming an aromatic cation of five- membered ring or six-membered ring together with nitrogen atom, L11 and L12 represent substitutional or non-substitutional alkylene group or alkenylene group, R11, R12 represent hydrogen atom or a substituent, n represents 0, or an integer, and X- represents anion. L21-L24 and L31-L36 are synonymous with L11. R31-R36 represents hydrogen atom or substituent. At least either one of R21-R24 represents a substituent expressed by -OM(OR)n. |
