An electrode (100) of the present invention contains a collector (104) and an electrode layer (102) which is disposed on the collector (104) and contains an active material. In the electrode (100), an average thickness (h) of the collector (104) and the electrode layer (102) ranges from 5 to 300 (m, and a maximum thickness (h) of the collector (104) and the electrode layer (102) is not more than 105% of a minimum thickness (h) of the collector (104) and the electrode layer (102). The electrode (100) is very thin and the uniformity of the electrode layer (102) is high. Therefore, the heat dissipation characteristics of the battery (300) are uniform, the local degradation is hardly generated in the battery (300), and the crack and the rupture are also hardly generated in the battery (300). |
