A tab is disposed in the first electrode plate and protrudes from the housing; and an adhesive layer is disposed in the tab. The adhesive layer includes a first portion sandwiched between a package area of the housing and a second portion extending from the first portion along a length direction of the tab. In a width direction of the tab, the first portion has a width greater than that of the second portion. In the length direction of the tab, the second portion protrudes into a space enclosed by an innermost layer of the separator.
