摘要：PROBLEM TO BE SOLVED: To greatly improve the quality of a metal cover manufactured capable of effectively preventing generation of a crack and reducing the umber of manufacturing processes. SOLUTION: In a cover 1, a valley part 8 and a protruded part 7 are respectively extended in a first direction A1, plural waved shapes 9 alternately connected are formed along a second direction A2 crossing the first direction A1, the protruded part 7 is constituted as integrating metal plates 4, 5 periodically changing their heights and widths along the first direction A1. In the metal cover 1 having a stereoscopic shape, the first direction A1 is set in the direction crossing a principal ridge line section 30 constituting a stereoscopic shape.
