An electrolytic solution for a non-aqueous electrolyte battery is provided, which is capable of providing an excellent low-temperature output characteristic at -30°C or lower and an excellent cycle characteristic at high temperatures of 45°C or higher. For example, the electrolytic solution contains the following salt having a divalent imide anion. wherein R 1 to R 3 represent a fluorine atom or an alkoxy group, for example, and M 1 and M 2 represent protons or metal cations, for example.
