SOLID-STATE BATTERY

The present invention provides a solid-state battery in which it is possible to more fully suppress connection failure between an electrode layer (i.e., a positive electrode layer and/or a negative electrode layer) and an end electrode. The present invention pertains to a solid-state battery 100A in which one or more positive electrode layers 1 and one or more negative electrode layers 2 are alternately stacked with a solid electrolyte layer 3 interposed therebetween, wherein: the solid-state battery has positive and negative end electrodes 4 (4a, 4b) at the end surfaces of the stacked structure; and the positive electrode layers and/or the negative electrode layers have, at the end part (A1, B1) on the side of the end electrode having the same polarity as the electrode layer in question, a concave-convex shape in plan view, and are electrically connected to the end electrode having the same polarity as the electrode layer in question. 本发明提供一种能够更充分抑制电极层(即，正极层和/或负极层)与端面电极的连接不良的固体电池。本发明涉及一种固体电池，具有由一个以上的正极层1以及一个
