Zusammenfassung:	To provide a manufacturing method of a solid electrolyte and a manufacturing method of a secondary battery which can reduce performance degradation.SOLUTION: In a manufacturing method of a solid electrolyte, an oxide having ionic conductivity and a complex hydride are dispersed in a solvent, and the solvent is removed to precipitate the complex hydride in the oxide. In a manufacturing method of a secondary battery, a solid electrolyte layer contains a solid electrolyte obtained by the above method. A secondary battery includes a positive electrode layer, a solid electrolyte layer, and a negative electrode layer in this order.SELECTED DRAWING: Figure 1 【課題】性能の低下を低減できる固体電解質の製造方法および二次電池の製造方法を提供する。【解決手段】固体電解質の製造方法は、イオン伝導性を有する酸化物および錯体水素化物を溶媒に分散し、溶媒を除去して錯体水素化物を酸化物に析出させる。二次電池の製造方法は、固体電解質層が、前記方法で得られた固体電解質を含む。二次電池は、順に、正極層、固体電解質層、負極層を含む。【選択図】図１
