SOLID-STATE BATTERY

The present invention provides a solid-state battery that has a solid-state battery stack having, along the stacking direction, at least one battery structural unit comprising a positive electrode layer, a negative electrode layer, and a solid electrolyte layer interposed between the positive electrode layer and the negative electrode layer. Said solid-state battery further has an external terminal of a positive electrode terminal and a negative electrode terminal that are respectively provided on the side surfaces of the solid-state battery stack. In the plan view of the solid-state battery, at least one of the electrode layers of the positive electrode layer and the negative electrode layer describes a tapered shape decreasing in dimension towards the side surface, of the side surfaces, for which the electrode layer contacts the external terminal. 本发明提供一种固体电池，具有：固体电池层叠体，沿层叠方向具备至少一个电池构成单元，电池构成单元具备正极层、负极层、及夹设于正极层和负极层之间的固体电解质层；以及正极端子及负极端子的外部端子，分别设于固体电池层叠体的侧面，在固体电池的平面视图中，正极层及负极层的电极层的至少一层形成尺寸朝向所述侧面中的该电极层与外部端子接触的
