Abstract:
An electric double-layer capacitor includes: a positive electrode containing a carbon material; a negative electrode containing a carbon material and a titanium oxide; and an electrolytic solution containing an ammonium salt. A weight ratio of the titanium oxide to the carbon material contained in the negative electrode is 2% by weight or more but not more than 50% by weight.
