Abstract
An exterior enclosure has an elevated portion forming a top plane. The elevated portion is surrounded by two pairs of mutually opposed ridge lines. The top plane is formed to have a concavely curved surface with respect to one of the two pairs of ridge lines. The exterior enclosure is manufactured by fixing a plate-shaped metallic blank material in place and pressing the blank material in a heated condition so that the elevated portion is formed with the top plane formed thereon. In the forming process of the elevated portion, the elevated portion is so formed as to have a concavely curved surface with respect to one of the two pairs of the ridge lines.
