<p>PROBLEM TO BE SOLVED: To provide an electrolyte which uses an electrolyte high in solubility to a polar solvent and is hardly decomposed, stable with time, low in specific resistance and high in spark generation voltage.SOLUTION: There is provided an electrolyte for an electrolytic capacitor, containing a compound represented by formula (1) or a salt thereof. HOOC-(CH)-O-(AO)-CH-O-(AO)-(CH)-COOH...(1) (In the formula (1), AO and AO each independently represent a 2-4C oxyalkylene group, each of ratios of an oxyethylene group in (AO)and (AO)is 50 wt.% or more, and x=2 to 50, y=2 to 50, m=5 to 12, (x+y)/m=1 to 15, a=1 to 3 and b=1 to 3 are satisfied.)</p> |
