Abstract
A lithium secondary battery anode member of the present invention includes a solid electrolyte film formed on a lithium metal film and is capable of suppressing reduction of the solid electrolyte film over a long period of time. In the lithium secondary battery anode member, the lithium metal film and the solid electrolyte film are laminated on a substrate, the solid electrolyte film contains the composition xLi.yP.zS.wO wherein x, y, z, and w satisfy the relations, 0.2≦x≦0.45, 0.1≦y≦0.2, 0.35≦z≦0.6, and 0.03≦w≦0.13, respectively, (x+y+z+w=1), and the main peaks of an X-ray diffraction pattern of the solid electrolyte film measured by a film method using Cu Kα radiation are at 2θ of about 11° and 30° and each have a half width of 10° or less.
