Original Abstract Submitted

A secondary battery includes a battery case, an electrode body, and a collector member connecting the battery case and the electrode body. A positive electrode includes an insulation layer provided so as to be adjacent to a positive electrode active material layer. The collector members include first portions, and second portions continuous to the first portions and bent relative to the first portions. The first portions are fixed to the battery case. The second portions are connected, at ends thereof opposite to the bent portions, to collector regions, respectively. The collector members further include ribs connected, at the bent portions, to the first portions and the second portions, respectively.
