Abstract

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