Abstract
A lithium ion conductive substance is provided that is characterized by containing a compound wherein a composite oxide represented by Li1+x+yAlxTi2−xSiyP3−yO12 (0≤x≤1 and 0≤y≤1) is doped with at least one kind of element selected from Zr, Hf, Y, and Sm. Furthermore, a method for manufacturing the lithium ion conductive substance is provided that includes the following steps: (a) a step of forming an inorganic substance that contains predetermined quantities of a Li component, an Al component, a Ti component, a Si component, and a P component, into a sheet shape, and (b) a step of interposing between materials that contain at least one kind of element selected from Zr, Hf, Y, and Sm, and sintering, a sheet-shaped formed body obtained at step (a).
