  "textContent": "A secondary battery includes a battery device to which a lead is coupled, a container, a cover part, and a first insulating part. The cover part includes first and second electrically conductive members. The cover part includes first and second joining regions in each of which the first and second electrically conductive members are mechanically joined to each other. In the first joining region, the first and second electrically conductive members are electrically coupled to each other. In the second joining region, the first and second electrically conductive members are electrically insulated from each other. A second joining strength with which the first and second electrically conductive members are joined to each other in the second joining region is higher than a first joining strength with which the first and second electrically conductive members are joined to each other in the first joining region.",
