<P>PROBLEM TO BE SOLVED: To provide a packing which is capable of reliably insulating a collector from a lid. <P>SOLUTION: An anode lower packing 17 has a rib 17h provided along the outer periphery of a flat part 17b on which a base part 12a of an anode collector 12 is to be disposed. A height H of the rib 17h is set equal to or greater than a thickness of the anode lower packing 17. The rib 17h may be provided only at a part of the outer periphery of the flat part 17b which correspond to a position where legs 12b and 12b protrude from the base part 12a of the anode collector 12. <P>COPYRIGHT: (C)2012,JPO&INPIT |
