Abstract: A negative electrode active material is represented by general formula M3Me2X7 (wherein M comprises at least one of La and Ca; Me comprises at least one element that is selected from the group consisting of Mn, Ni, Fe and Co; and X comprises at least one element that is selected from the group consisting of Ge, Si, Sn, and Al). With respect to the XRD pattern obtained by XRD measurement wherein Cu is used for an anticathode, the half-value width of the diffraction peak of the (1 171) plane of the negative electrode active material is 0.4713° or more.
