PURPOSE: An electrolyte for an aluminum electrolytic capacitor is provided to improve a low temperature feature and a high temperature life feature of an electrolytic capacitor by composing pH of the electrolyte within 3.5-7 with a maleic acid and a triethylamine. CONSTITUTION: The electrolyte for an aluminum electrolytic capacitor includes a γ butyl lactone of 60-65 weight %, an ethylene glycol of 6-8 weight %, a phthalic acid of 10 weight %, a triethylamine of 10-17 weight %, a boric acid of 1.0-5.0 weight %, a sorbitol of 3.0-8.0 weight %, a p-nitro benzo phosphate of 1 weight %, an aromatic nitro compound of 0.5-1.0 weight %. The electrolyte for an aluminum electrolytic capacitor miniatures an electrolytic capacitor, stabilizes a high temperature to enlarge usage temperature range. A conductive degree of the electrolyte for an aluminum electrolytic capacitor is 6.0mS/cm. An internal voltage of the electrolyte for an aluminum electrolytic capacitor is 120V.
