Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a nonaqueous electrolyte having a high withstand voltage and can maintain high reliability for a long period and an electrochemical capacitor using the electrolyte. SOLUTION: An electrolyte is prepared by dissolving an electrolytic salt containing a tetrafluoroborate as the main component in a nonaqueous solvent and the total content of hydrolyzates in the BF4- portion of the tetrafluoroborate in the electrolyte is adjusted to
