ELECTROLYTE FOR DRIVING ELECTROLYTIC CAPACITOR, AND ELECTROLYTIC CAPACITOR USING THE SAME

PROBLEM TO BE SOLVED: To obtain an electrolytic-capacitor-driving electrolyte wherein elution is not generated even at a low temperature and its characteristic is stabilized even at a high temperature and its reliability is improved, by dissolving in a solvent having an organic compound as its main component one or more kinds of inorganic and organic acids and salts thereof as solutes, and further dissolving additionally in this solution a specific copolymer. SOLUTION: In a solvent having an organic compound as its main compact, one or more kinds of inorganic and organic acids and salts thereof are dissolved as solutes. Further, in this solution, there is dissolved additionally a copolymer represented by the following chemical formula: R-O-[(A)n -(B)m ]l-H, wherein n, m, 1: arbitrary natural number, R:CH3 , C2 H5 , C3 H7 , C2 H4 (CH3 ), C4 H9 , C3 H6 (CH3 ), C5 H11 , C4 H8 (CH3 ), C3 H5 (CH3 )2 , A, B:C2 H4 O, C3 H6 O, C4 H8 O, C2 H4 (CH3 ) O, C3 H5 (CH3 )O, C2 H4 (CH3 )2 O, but, A and B are different monomers}.
