An all-solid battery including a solid electrolyte layer capable of suppressing generation of hydrogen sulfide and suppressing a decrease in ionic conductivity is provided. An all-solid battery according to the present invention includes a positive electrode, a negative electrode, and a solid electrolyte layer mainly composed of a solid electrolyte between the positive electrode and the negative electrode, and the solid electrolyte is a sulfide-based solid electrolyte. In the solid electrolyte layer, an alkaline compound is mixed in the solid electrolyte, and a ratio of a molar amount of the alkali metal contained in the alkaline compound to a molar amount of Li contained in the solid electrolyte is 1/1000 or more. / 25 or less.
