Original Abstract Submitted
a secondary battery includes a stacked body including a positive electrode, a negative electrode, and a separator. the positive electrode includes a positive electrode active material layer, a positive electrode current collector, and an insulating layer. the positive electrode current collector includes a positive electrode covered region and a positive electrode exposed region. the positive electrode exposed region is not covered with the positive electrode active material layer and extends in a width direction from the positive electrode active material layer. the insulating layer extends along a first edge of the positive electrode active material layer. the first edge is located at a border between the positive electrode covered region and the positive electrode exposed region. the positive electrode active material layer includes a first thin part and a first thick part that is adjacent to the first thin part in the width direction.
