Abstract
A method is provided for preparing an all-solid battery that at least includes a negative electrode layer containing a negative electrode active material and a sulfide solid electrolyte, and a negative electrode current collector containing a metal that is in contact with the negative electrode layer and can react with the sulfide solid electrolyte, in which a sulfur compound generated by a reaction of the metal contained in the negative electrode current collector and the sulfide solid electrolyte contained in the negative electrode layer is not present in a contact portion of the negative electrode layer and the negative electrode current collector.
