<P>PROBLEM TO BE SOLVED: To obtain a cylindrical battery which can simply and sufficiently ensure an electrical conduction between a positive electrode collector member and a lid, and can be easily assembled. <P>SOLUTION: A cylindrical battery 1 comprises a lid case (connection member) 35 electrically connecting a positive electrode collector member 40 and a lid 31 in the state of being interposed therebetween. The lid case 35 is fixed to the positive electrode collector member 40 in the state that a contact pressure is applied to a contact area between the positive electrode collector member 40 and the lid case 35 by being press-contacted to the positive electrode collector member 40, and is electrically connected to the positive electrode collector member 40. <P>COPYRIGHT: (C)2012,JPO&INPIT |
