The purpose of the present invention is to provide a power storage element in which impurity contamination of the interior of a packaging body, when a reference electrode part is provided within the packaging body, is minimized. The power storage element (1) is provided with a power storage element (3), the packaging body (2) comprising a conductor which is electrically insulated from the power storage element (3), and the reference electrode part (42), the reference electrode part (42) being configured such that a reference electrode mixture is directly formed on the inner surface of the packaging body (2). This makes it possible to minimize generation of packaging body (2) fragments and prevent generation of fragments from the reference electrode part (42) when the reference electrode part (42) is formed within the packaging body (2). As a result, it is possible to minimize impurity contamination in the interior of the packaging body (2). |
