摘要： Disclosed is a capacitor that is not easily degraded to stably maintain the performance for a long time. The electrochemical capacitor includes a first electrode provided in a rolled sheet form and having active material layers coated on both surfaces thereof; a second electrode provided in a rolled sheet form at an outer side of the first electrode to face the first electrode and having active material layers coated on both surfaces thereof; and a separator interposed and rolled between the first electrode and the second electrode, wherein at least a portion of an outermost layer of the first electrode is exposed to the outside.
