| 1. A capacitor device containing a plurality of capacitors,
each of the capacitors comprising a capacitor element having a positive electrode and a negative electrode in a confronting
arrangement through a separator, and a metal case containing the capacitor element and an electrolyte,
the plurality of capacitors comprising a plurality of first capacitors, each using the metal case as a negative electrode
thereof, and a plurality of second capacitors, each using the metal case as a positive electrode thereof,
wherein each of a plurality of capacitor units is formed by one of the first capacitors and one of the second capacitors with
their metal cases coupled together through a metal plate,
each of a plurality of subunits is formed by a plurality of the capacitor units connected in any of series and parallel, and
a main unit of the capacitor device is formed by the plurality of subunits connected in any of series and parallel.
