Abstract
In an all-solid secondary battery, in an electrode active material layer of at least one of positive and negative electrode bodies, a total content ratio, which is represented by a ratio of mass of an electrolyte contained in the electrode active material layer to mass of an active material contained in the electrode active material layer, is larger than 1; and the electrode active material layer of the at least one of the positive and negative electrode bodies has a composition distribution in which a local content ratio, which is represented by a ratio of mass of the electrolyte contained in a portion of the electrode active material layer to mass of the active material contained in the portion of the electrode active material layer, increases from a solid electrolyte interface toward a current collector interface in a thickness direction of the electrode active material layer.
