Abstract
In an electrode for a lithium battery having a lithium storing and releasing active thin film provided on a current collector, such as a microcrystalline or amorphous silicon thin film, the electrode is characterized in that the thin film is divided into columns by gaps formed therein in a manner to extend in its thickness direction and that the columnar portions are at their bottoms adhered to the current collector.
