Abstract
An electrode body which achieves not only high initial capacitance of an electrolyte capacitor but also achieves stable capacitance even after being exposed to high temperature environment, and the electrolyte capacitor including the electrode body are provided. The electrode body is used for a negative electrode of the electrolyte capacitor, and the electrode body includes a negative electrode foil formed by a valve action metal, and a carbon layer formed on the negative electrode foil. The carbon layer includes a first spherical carbon and a second spherical carbon, and the first spherical carbon has a BET specific surface area larger than the second spherical carbon.
