Abstract
An all-solid-state battery includes a positive electrode layer, a negative electrode layer, a solid electrolyte layer disposed between the positive electrode layer and the negative electrode layer, and an insulating layer disposed on an outer periphery of the positive electrode layer. The solid electrolyte layer includes the inner layer portion disposed inside the boundary between the outer periphery of the positive electrode layer and the insulating layer in plan view, and the outer layer portion disposed on the outer periphery of the inner layer portion in plan view and overlapping the insulating layer. The outer layer portion has a lower ionic conductivity than the inner layer portion.
