To house an electrode body in an outer can so as not to move, and simply, surely connect a current collecting tab to the outer can.

This sealed battery is formed by arranging a spirally wound electrode body 2 in the inside of an outer can. Positive and negative electrode plates of the electrode body 2 are connected to the outer can and a terminal plate respectively. The outer can is constituted with a cylinder 1A and a bottom plate 1B which are produced as the separate parts, a current collecting tab 3 whose part is connected to one electrode plate of the electrode body 2 is connected to the bottom plate 1B, and the bottom plate 1B connected to the current collecting tab 3 is fixed airtightly to the bottom of the cylinder 1A for forming the outer can.
