摘要:
An electric chemical capacitor includes first and second electrodes each including a collector 111, 121, a polarized electrode layer 112, 122 and an undercoat layer 113, 123 for bonding the collector and the polarized electrode layer with each other, and a separator put between the first and second electrodes so that the polarized electrode layers 112 and 122 face each other, wherein an end portion of each undercoat layer 113, 123 is located in the same position as or on the outer side of an end portion of the corresponding polarized electrode layer 112, 122, and located on the inner side of an end portion of the separator 130. Thus, the polarized electrode layers can be prevented from peeling from the collector. Further, the undercoat layers can be prevented from abutting against each other, and the undercoat layer of one electrode and the collector of the other electrode can be prevented from abutting against each other.
