Abstract
A solid electrolyte structure (1) for all-solid-state batteries includes a plate-like dense body (2) formed of a ceramic that includes a solid electrolyte, and a porous layer (3) formed of a ceramic that includes a solid electrolyte that is the same as or different from the solid electrolyte of the dense body (2), the porous layer (3) being integrally formed on at least one surface of the dense body (2) by firing. The solid electrolyte structure can reduce the contact resistance at the interface between the solid electrolyte and an electrode.
