    摘要： There is disclosed an electrotlyte for electrolytic capacitor containing a carboxylic acid salt of a cationic nitrogen-­containing heterocyclic compound as a solute within an aprotic solvent or a mixed solvent comprising major aprotic solvent and minor polyol solvent.
    An electrolyte for electrolytic capacitor according to the present invention may conveniently be prepared in such a way that pyrrolidinium hydrogensulfate, piperidinium hydrogensulfate or pyridinium hydrogensulfate is dissolved in a solvent such as methyl acetate or methly chloride, and an equivalent amount of objective carboxylic acid is added, then an hydroxyalkali metal in two equivalent amounts is added to react, the depositions are removed to obtain an anhydrous salt by drying under vacumm and the resulting one is dissolved in a specific solvent in a concentration at which a desired conductivity may be obtained.

    摘要： An electrolytic capacitor (10) of the present invention is so constituted that a capacitor element (12) steeped with an electrolytic solution containing quaternary ammonia salts is accommodated in an armor case (16) of which aperture is sealed with a sealing body (22). To achieve the above object, an external terminal (14) of the electrolytic capacitor (10) has a contact surface contacting with the sealing body (22) and being coated by a ceramic coating layer (34).
