Abstract

A solid electrolyte for a secondary battery includes a core phase having a particle shape and a shell phase covering at least a part of the core phase. The shell phase consists of one or more phases. A constituent material of the core phase includes a pyrochlore solid electrolyte represented by a composition formula of AaAbBOX, where Aa is an alkali metal, Ab is a lanthanoid, B is a cationic metal, and X is an anion that is substitutable with O. A constituent material of the shell phase includes a material having a chemical composition including Li and different from a chemical composition of the pyrochlore solid electrolyte, and having a melting point lower than a melting point of the pyrochlore solid electrolyte.
