An object of the present invention is to reduce a useless space that does not contribute to power generation mainly in the vicinity of a sealing structure in a sealed power storage device and to improve volume energy density. A sealed electricity storage comprising an electrode body (9) comprising a positive electrode body (3), a negative electrode body (5) and a separator (7), and an outer case (11) for housing the electrode body (9). In the apparatus, the outer case (11) is a bottomed cylindrical case body (13) that also serves as a terminal of one electrode, and the lead (21) of the other electrode is inserted into the bottom (13a). A case main body having a hole (23), a flat electrode terminal member (15) constituting a terminal of the other electrode, the flat electrode terminal member (15), and a bottom (13a) of the case main body (13); An insulating material that is interposed between the flat electrode terminal member (15) and adheres to the outer surface of the bottom (13a) of the case body (13) so as to cover the insertion hole (23). The formed adhesive seal member (17) is provided. [Selection] Figure 1 |
