摘要：
There are provided an electrolytic solution for electrolytic capacitor comprising a quaternary cyclic amidinium tetrafluoroaluminate and a solvent and containing specific impurity compounds in a total amount of 0.6% by weight or less; an electrolytic capacitor using the electrolytic solution; and a method for preparing an organic onium tetrafluoroaluminate which is advantageously used in an aluminum electrolytic capacitor.
