Abstract
A power storage device includes an electrode assembly formed by stacking a positive electrode sheet, a negative electrode sheet, and a sheet-like separator arranged between the positive and negative electrode sheets. The positive electrode sheet includes a positive electrode thin metal plate, which includes a first positive electrode edge and a second positive electrode edge. A surface of the positive electrode sheet includes a positive electrode application region and a positive electrode non-application region. The negative electrode sheet includes a negative electrode thin metal plate including a first negative electrode edge and a second negative electrode edge. A positive electrode border, which is a border between the positive electrode application region and the positive electrode non-application region, is located between the first positive electrode edge and the second positive electrode edge. The positive electrode border is located between the first negative electrode edge and the second negative electrode edge.
