Abstract: A garnet-type Li-ion conductive oxide containing LixLa3Zr2O12 (6≦x≦8) contains Al and element T (T is one or more from Ni, Cu, Co, and Fe). The content of Al is, in terms of Al2O3, 2.5 mol %≦Al2O3≦15 mol % with respect to a total amount of LixLa3Zr2O12 contained in the garnet-type Li-ion conductive oxide. The content of element T is 25 mol %≦T≦100 mol % with respect to the total amount of LixLa3Zr2O12 contained in the garnet-type Li-ion conductive oxide.
