Since the embossing is irregular or the embossing position is significantly biased, the formation of a curved surface is significantly hindered. As a result, there is a high possibility that a joining defect will occur as compared with the above reference example. In addition, it is difficult to predict the details of curved surface formation defects at the design stage. Therefore, the effect of forming the polygonal line L (described later) becomes remarkable.
