Original Abstract Submitted

A solid-state battery according to this disclosure is a solid-state battery including a first current collector layer, a first active material layer, a separator layer, a second active material layer, a second current collector layer, and an insulating layer that are laminated in this order. The first current collector layer is wound on a laminated body including the first active material layer, the separator layer, the second active material layer, the second current collector layer, and the insulating layer to surround the laminated body. The first current collector layer forms an outer packaging body such that overlapped parts of the first current collector are joined to each other at a position overlapping with a surface of the laminated body in its lamination direction.
