PROBLEM TO BE SOLVED: To obtain an accumulative rubber (electrode) that mainly includes a rubber and does not depend on the retention of a mechanical strength on a collector by utilizing adhesion and flexibility inherently present in the rubber, and to obtain the electrode without using a coating process onto the collector. SOLUTION: The accumulative rubber, wherein (1) an ion conductive dispersant and an electron conductive dispersant are dispersed in a rubber support, (2) pores into which an ion conductive liquid is permeated are uniformly dispersed in the rubber support, and the electron conductive dispersant is dispersed. (3) the electrode accumulative rubber, wherein a cell active substance is further dispersed in (1) the accumulative rubber, and (4) the electron conductive dispersant and a cell active substance are dispersed in the rubber support not containing the ion conductive dispersant. In addition, the accumulative rubber and a collector are bonded together which are collectively used for the electrical double layered capacitor or a lithium cell. COPYRIGHT: (C)2006,JPO&NCIPI
