<p>An injection hole (111) is closed off with a sealing member (130) and a hermetic plug (120). An outer diameter d2 of a flange-shaped part (132) of the sealing member (130) which is inserted in the injection hole (111) is smaller than a diameter d1 of the injection hole (111). The hermetic plug (120), comprising a cylindrical part (121) which has an outer diameter d4 which is greater than a diameter d5 of a hollow part (135) of the sealing member (130), is fitted in the hollow part (135). Accordingly, a cylindrical-shaped part (131) of the sealing member (130) is pressed into, and compressed in, a peripheral edge part lateral face of the injection hole (111) of a battery lid (102), by an outer circumference face of the cylindrical part (121) of the hermetic plug (120). In such a state, the outer circumference of a flange part (122) of the hermetic plug (120) is welded to the battery lid (102).</p> |
