A capacitor has stacking capacitor elements, each of which contains a
conductor plate, a first band being an insulator and disposed around the
plate, a second band being an insulator and disposed around the plate so
as to be substantially parallel to the first band, an insulating coating
covering a region sandwiched between the first and second bands, a
cathode layer formed on the insulating coating, and an anode containing
the plate and formed on an outer side of at least one of the first and
second bands. The cathode layers are elctrically connected to each other
through paths each connecting in series the facing two cathode layers of
the adjacent two elements and path(s) connecting in parallel the cathode
layers to each other, and the anodes are electrically connected to each
other through path(s) connecting in parallel the anodes to each other.
