摘要:
A panel-shaped formed product (1) made of a metal sheet includes a top panel portion (2), an opening portion (3), and a vertical wall portion (4). The top panel portion (2) is polygonal. The opening portion (3) is provided in the top panel portion (2). The vertical wall portion (4) extends from at least not less than two adjacent borders among the borders of the top panel portion (2). At least one pair of each vertical wall portion (4) of pairs of adjacent vertical wall portions (4) of the vertical wall portions (4) has a stepped portion (5). As a result, the panel shaped formed product (1) has fewer defects such as cracks and wrinkles even when it has a shape that is difficult to form.
