The present invention relates to an all-solid-state battery comprising: a cathode which includes a cathode current collector coated with a cathode mixture layer; an anode which includes an anode current collector having a porous structure; a solid electrolyte layer which is disposed between the cathode and the anode; a stopper which is disposed at the outer circumference of the anode; a battery case in which the stopper and an electrode assembly including the cathode, the anode, and the solid electrolyte layer are accommodated; and pressure members which are disposed at both surfaces of the battery case parallel to the planes of the cathode and the anode and press the cathode and the anode toward the inside of the battery case, wherein the height of the stopper has a size equal to or smaller than the thickness of the anode before being pressed. The all-solid-state battery suppresses the formation of lithium dendrites and thus has improved safety.
