Abstract: A solid-state battery package that includes: a substrate; and a solid-state battery on the substrate. The solid-state battery has: a battery element having a positive electrode layer, a negative electrode layer, and a solid electrolyte; and an end-face electrode on an end face of the battery element and connected to one of the positive or negative electrode layers. The substrate has a substrate electrode layer on a main surface thereof, and at least a first side surface of the substrate electrode layer and a first end face of the end-face electrode are substantially on an identical line in a sectional view, a distance between the first side surface and a second side surface of the substrate electrode layer is equal to or more than a minimum distance between the first end face and an end surface of the positive or negative electrode layer that the end-face electrode is not connected.
