Abstract
The stacked battery includes a negative electrode () and a positive electrode (). The negative electrode has a negative electrode main portion () and a negative electrode lead (). The positive electrode has a positive electrode main portion () and a positive electrode lead (). The negative electrode main portion and the positive electrode main portion are stacked in a thickness direction with the negative electrode lead and the positive electrode lead extending in different directions as viewed from above. The positive electrode lead is fixed to a positive electrode case. In the positive electrode lead, a break place (X) is provided outside the negative electrode main portion as viewed from above when the negative electrode and the positive electrode are placed on top of each other. The break place (X) is broken when a shock is applied to the electrodes.
