PROBLEM TO BE SOLVED: To provide an electrolytic capacitor driving electrolyte, with which the deformation of external appearance of the electrolytic capacitor due to the thermal stress when a surface mounting operation is performed, can be suppressed. SOLUTION: An electrolytic capacitor, on which the deformation of external appearance due to the thermal stress generated when surface mounting treatment is performed, is suppressed, can be accomplished by obtaining an electrolytic capacitor driving electrolyte of the constitution, wherein organic acid salt is dissolved as an electrolyte into organic solvent containing N-methyl-N-alkyl-2- imidazol (provided that the carbon number of N+-alkyl radical is 2 or more). |
