The present invention prevents edge collapse of an electrode layer of a laminated body included in an all-solid-state battery. A method of producing an all-solid-state battery includes: a laminated body forming step of forming a laminated body () including (i) a positive electrode layer (), (ii) a negative electrode layer () having a polarity opposite of a polarity of the positive electrode layer (); and (iii) a solid-electrolyte layer () disposed between the positive electrode layer () and the negative electrode layer (); and a cutoff step of cutting off an outer peripheral edge of the laminated body () so as to form a laminated body containing a powder material.
