Abstract
[Object] To provide an all-solid-state battery including an all-solid-state battery laminate which is covered with a resin layer, in which cracking of the resin layer due to changes in volume of the all-solid-state battery laminate can be prevented. [Solution To Problem] Provided is an all-solid-state battery, including an all-solid-state battery laminate including at least one all-solid-state unit cell obtained by laminating a positive electrode current collector layer, a positive electrode active material layer, a solid electrolyte layer, a negative electrode active material layer, and a negative electrode current collector layer in this order, and a resin layer, wherein the resin layer covers at least the side surfaces of the all-solid-state battery laminate, and a cavity is present between the side surfaces of at least the negative electrode active material layer and the resin layer.
