Abstract: An LLZ oxide may be a garnet-type oxide that contains Li, La, Zr and O as main constituent elements, and further contains substituent elements such as Zn in addition to the main constituent elements. The substituent elements may contain Bi, Nb, Hf and the like in addition to Zn. The LLZ-type oxide may be used, for example, as a solid electrolyte for an all-solid-state lithium ion secondary battery. The all-solid-state lithium ion secondary battery includes a positive electrode, a negative electrode, and a solid electrolyte layer that is disposed between the positive electrode and the negative electrode.
