PCT No. PCT/JP96/00473 Sec. 371 Date May 2, 1997 Sec. 102(e) Date May 2, 1997 PCT Filed Feb. 29, 1996 PCT Pub. No. WO96/27201 PCT Pub. Date Sep. 6, 1996The invention relates to an electrolyte for driving electrolytic capacitor and an electrolytic capacitor using the same, and by preparing by using a solvent mainly composed of organic compound, and dissolving one or more solutes selected from the group consisting of inorganic acids and organic acids, more specifically adding and dissolving at least one of copolymers of polyethylene glycol and polypropylene glycol shown in formulas (1) and (2), or both of the copolymers of polyethylene glycol and polypropylene glycol shown in formulas (1) and (2) simultaneously, the spark generation voltage and chemical conversion factor of formed oxidation film are enhanced, thereby improving the reliability of the electrolytic capacitor.HO-(C2H4O)n-(C3H6O)m-(C2H4O)n-H(1)(n and m are arbitrary natural numbers.)HO-[(C2H4O)n-(C3H6O)m]i-H(2)(n, m, and 1 are arbitrary natural numbers.)
