摘要：
Having a current collector having a concave portion and a convex portion at least on one side, and a columnar body formed on the convex portion of the current collector, the columnar body contains an active material for inserting and extracting lithium ions bonding at least with oxygen, and the oxygen content ratio of the active material of the columnar body becomes smaller as going away from the interface of the current collector.
