PROBLEM TO BE SOLVED: To provide an electrolytic solution for driving an electrolytic capacitor which electrolytic solution suppresses a rise in an internal pressure to inhibit an increase in a product height and the deformation of an outer packaging case, even under a condition giving a high set temperature of flow/reflow in using a lead-free solder. SOLUTION: An organic carboxylic acid or an organic carboxylic acid chloride, and a 3-propanol-1, 3-thiazolidine-4-carboxylic acid of 5.0 to 10.0 wt% which is represented by the chemical formula 1, are dissolved into a solvent mainly composed of aγ-butyrolactone.
