ALL-SOLID-STATE BATTERY

An all-solid-state battery includes: a laminate including a first surface and a second surface facing each other in a first direction, a positive electrode layer, a negative electrode layer, and a solid electrolyte layer disposed between the positive electrode layer and the negative electrode layer and including a solid electrolyte; a first thin-film electrode that is directly connected to the positive electrode layer and the solid electrolyte layer on the first surface of the laminate; a second thin-film electrode that is directly connected to the negative electrode layer and the solid electrolyte layer on the second surface of the laminate; a first external electrode that is connected to the first thin-film electrode and covers at least a portion of the laminate; and a second external electrode that is connected to the second thin-film electrode and covers at least a portion of the laminate.
