Abstract
Abstract A laminated structure comprises a plurality of double-layer capacitor unit cells, each having a high withstand voltage. A complete capacitor is made by laminating a plurality of unit cells of the double-layer capacitors type and by connecting a plurality of resistors, having substantially equal resistances, in parallel with the respective unit cells. In a preferred embodiment, a high-precision integrated voltage-equalizing resistor is prepared by laying linear resistors on a flexible sheet which is then wrapped around the laminated unit cells.
