Abstract
In the corrugated metal sheet 5 in which the crest portions 5a and the trough portions 5b are formed in plural alternatively along the corrugation direction 61, the rack portions 5f, the rising trough portions 5d, and the rising crest portions 5e are provided in plural. The rack portions 5f are arranged between the crest portions 5a and the trough portions 5b and extended along the folding direction 60 and the corrugation direction 61 to couple adjacent crest portions 5a and trough portions 5b. The rising trough portions 5d are folded from the boundaries between the crest portions and the rack portions 5f such that part of the crest portions 5a being divided by two cuttings separated in the folding direction 60 are protruded partially in the same direction as the trough portions 5b. The rising crest portions 5e are folded from the boundaries between the trough portions and the rack portions 5f such that part of the trough portions 5a being divided by two cuttings separated in the folding direction 60 are protruded partially in the same direction as the crest portions 5b.
