摘要： A lithium secondary battery (10) provided by the present invention has an iron oxide film-coated electrode employing a configuration in which an iron oxide film (144) capable of reversibly absorbing and desorbing lithium is retained on an electrically conductive base (142). The electrically conductive base (142) has a roughened surface having a surface roughness Rz of 3 µm or more, and the iron oxide film (144) is provided on the roughened surface.
