Abstract: A method for generating smoke in a cell pack by which a very small amount of smoke can be generated from a specific single unit cell among unit cells constituting the cell pack. The method causes smoke generation in a cell pack in which unit cells are connected and which includes a positive electrode output terminal for electrically connecting the positive electrode terminal of the unit cell and an external device, and a negative electrode output terminal for electrically connecting the negative electrode terminal of the unit cell and an external device. By attaching a heating means to the negative electrode output terminal, the electrode body of a specific single unit cell is heated through the negative electrode output terminal to which the heating means is attached. As a result, it is possible to cause the generation of a small amount of smoke from the specific single unit cell.
