There is provided an organic electrolyte capacitor having electrodes on
current collectors that have holes penetrating the front and rear
surfaces, in which electrode materials formed on the through-holes of the
current collectors seldom fall off and high energy density and high power
density can be obtained. The organic electrolyte capacitor includes
positive electrodes, negative electrodes and an electrolyte capable of
transferring lithium ions, in which the positive electrodes contain a
substance capable of carrying lithium ions and/or anions reversibly as a
positive electrode active material, the negative electrodes contain a
substance capable of carrying lithium ions as a negative electrode active
material, the positive and negative electrodes possess the positive or
negative electrode active material layers on an electrode substrate that
has conductive layers made of conductive materials on current collectors,
which have through-holes, and the negative electrodes carry lithium
electrochemically.
