Beschreibung
Zusammenfassung:	A metallic worked article suppressing the worked surfaces from being scratched during the plastic work that is conducted aiming at reducing the thickness or decreasing the diameter. The metallic worked article has a reduced thickness or a decreased diameter as obtained through the plastic work, wherein on the worked surface thereof, the ratio Ra1/Ra2 of an arithmetic mean roughness Ra1 measured in a direction at right angles with the direction of working and an arithmetic mean roughness Ra2 measured in the direction of working, is from 0.5 to 1.5.
