Abstract
Provided is an all-solid-state battery capable of suppressing a rise in the resistance increase ratio thereof. The all-solid-state battery includes an anode active material layer containing an alloy-based active material, a first fibrous carbon, and a second fibrous carbon, wherein when a fiber diameter of the first fibrous carbon is defined as A, and a fiber diameter of the second fibrous carbon is defined as B, the ratio of A to B is 10 to 300, and when the proportion (wt %) of the first fibrous carbon to the alloy-based active material is defined as X, and the proportion (wt %) of the second fibrous carbon to the alloy-based active material is defined as Y, the proportion ({Y/(X+Y)}×100%) of the contained second fibrous carbon to a total of the first fibrous carbon and the second fibrous carbon is 0.5% to 10%.
