PROBLEM TO BE SOLVED: To provide a composite solid electrolyte free from the generation of cleavage and cracks, and in which flexibility and ion conductivity are made consistent.SOLUTION: Provided is a composite solid electrolyte body having the first face and the second face and in which lithium ions are conducted in a space between the first face and the second face, a plurality of inorganic solid electrolyte bodies having lithium ion conductivity are bound with a binder other than the inorganic solid electrolyte, some of a plurality of the inorganic solid electrolyte bodies being conductive passage constituting inorganic solid electrolyte bodies composing a lithium ion conductive passage continuous from the first face to the second face, and the ratio of the area of a plurality of the inorganic solid electrolyte bodies exposed to the first face to the area of the binder exposed to the first face is 0.25 to 500. |
