<P>PROBLEM TO BE SOLVED: To prevent the fixed position of a power generation element having cathode and anode electrodes from being displaced toward a battery lid to a can bottom direction in the battery container. <P>SOLUTION: A battery lid 3 has a cathode external terminal 61, a cathode terminal 63 and a cathode connection terminal 62 fixed in place along with a gasket 65 and an insulating plate 64. Furthermore, the cathode connection terminal 62 has a cathode collector plate 21 fixed thereto by caulking. A position restraint member 22 formed with an insulating material has a locking piece 22a attached to the cathode collector plate 21 through an opening 21d in the cathode collector plate 21. The position restraint member 22 has one side edge 40a in the longer direction of a power generation element 40 abutting thereon, and in this state, the power generation element 40 is joined to the cathode collector plate 21 and an anode collector plate 31. <P>COPYRIGHT: (C)2013,JPO&INPIT |
