description PROBLEM TO BE SOLVED: To improve the chemical convertion without lowering the conductivity of a driving electrolyte by adding polyetylene glicol, polyglycerin and their copolymer to a solvent comprising organic materials with particular acids or their salts as a solute for dissolution thereby restricting the rise in internal pressure in an electrolytic capacitor case. SOLUTION: One, two or more kinds of acids or salts selected from equations I or II are used as main solute and further one kind of more selected from polyethylene glycol, polygrycerin and their copolymers are added and dissolved. Acids or their salts selected from the equations I and II are excellent in chemical conversion compared with dibasic acid, so that spark generating voltage can be improved. Moreover, complex forming reaction with aluminum foil is smaller than that of the dibasic acid, so that gas generation or corrosion is hard to occur, moreover, by the effect of hydroxyl in the molecule of high polymer compound, film resistance concentrated near the anodic aluminum foil can be increased.
