[Problem] To provide a hybrid capacitor with which there is safety and robustness, and it is possible to obtain high energy density with high cell voltage. [Solution] A hybrid capacitor comprises at least: a positive electrode (11) having a carbon material and/or a metallic oxide
a negative electrode which is configured of a lithium composite electrode
and a neutral aqueous electrolyte (13) which is filled between the positive electrode (11) and the negative electrode (12). The lithium composite electrode (12) is configured to be a layered electrode of a lithium ion conductive solid-state electrolyte (21), a polymer electrolyte (22), and an active material layer (23) including lithium, thus solving the problem. It is desirable for the neutral aqueous electrolyte (13) to have a ph of 5-8.5, and for the metallic oxide to be chosen from manganese oxide, ruthenium oxide, or lead oxide.
