A laminated all-solid-state battery includes a laminate having positive electrode and positive electrode active material layers, negative electrode layers having negative electrode current collector and negative electrode active material layers, and solid electrolyte layers. The positive and negative electrode layers are alternately laminated with the solid electrolyte layers interposed. The solid electrolyte layers include solid electrolyte layers belonging to first and second groups, the second thicker than the first. The first group includes a first solid electrolyte layer being thinnest. The second group is composed of a second solid electrolyte layer having a thickness of twice or more that of the first. A relationship (1) is satisfied when an average thickness of the plurality of solid electrolyte layers belonging to the first group is defined as tand an average thickness of the solid electrolyte layers belonging to the second group is defined as t; 2t≤t. . . (1).
