PROBLEM TO BE SOLVED: To provide an aluminium electorlytic capacitor, which is superior in an electric conductance and a sparking voltage and prevents liquid leakage, by a method wherein an electrolyte for aluminium electrolytic capacitor drive uses an aromatic or aliphatic carboxylic acid imidazoline salt, which contains an imidazoline compound, which is shown by a specified formula, as its cation component, as its solute. SOLUTION: This electrolyte is an electrolyte using an aromatic or apliphatic carboxylic acid imidazoline salt, which contains an imidazoline compound, which is shown by the formula, as its cation component, as its solute. It is preferable that an aromatic carboxylic acid is a phtalic acid, an benzoic acid, a salicylic acid or a resorcilic acid, but the aromatic carboxylic acid is not limited to these acids. it is preferable that an aliphatic acid is a maleic acid, a citraconic aicd, a fumanic acid or a maloic acid, but the alphatic acid in not limited to these acids. As the imidazoline compound which is shown by the formula, dimethyl imidazoline, a diethyl imidazoline, a methyl-ethyl imidazoline and a dipropyl imidazoline are preferable, but the imdazolne compound is not limited to the above compounds. Further, it is preferable that the electrolyte uses a nonprotic solvent as its solvent.
