What is claimed is: 1 . A garnet-type Li-ion conductive oxide comprising Li x La 3 Zr 2 O 12 (6≦x≦8) and containing Al and element T (T is one or more from Ni, Cu, Co, and Fe), wherein the content of Al is, in terms of Al 2 O 3 , 2.5 mol %≦Al 2 O 3 ≦15 mol % with respect to a total amount of Li x La 3 Zr 2 O 12 contained in the garnet-type Li-ion conductive oxide, and the content of element T is 25 mol %≦T≦100 mol % with respect to the total amount of Li x La 3 Zr 2 O 12 contained in the garnet-type Li-ion conductive oxide. 2 . A garnet-type Li-ion conductive oxide comprising Li x La 3 Zr 2 O 12 (6≦x≦8) and containing Al 2 O 3 and M (M is one or more oxides selected from NiO, CuO, CoO 4/3 , and FeO 3/2 ), wherein the contents of Al 2 O 3 and M with respect to a total amount of Li x La 3 Zr 2 O 12 contained in the garnet-type Li-ion conductive oxide are such that 2.5 mol %≦Al 2 O 3 ≦15 mol %, and 25 mol %≦M≦100 mol %. 3 . An all-solid Li-ion secondary battery comprising the garnet-type Li-ion conductive oxide according to claim 1 as a solid electrolyte. 4 . An all-solid Li-ion secondary battery comprising the garnet-type Li-ion conductive oxide according to claim 2 as a solid electrolyte.
