A winding battery includes a positive electrode plate and a negative electrode plate which are formed by winding, the positive electrode plate includes a positive electrode current collector and a first coating layer, and the negative electrode plate includes a negative electrode current collector and a negative electrode active layer. The first coating layer includes a first insulating adhesive layer and a positive electrode active layer, the positive electrode active layer is disposed on a surface of the positive electrode current collector, the first insulating adhesive layer is connected to the positive electrode active layer, and at least one cross section of the first insulating adhesive layer and an end surface, close to a winding start point, of the negative electrode active layer are located in a same plane.
