Abstract
A method of preparing a cylindrical metal member includes preparing a metallic ingot having at least one surface having a mean width with respect to roughness Sm in a range of from 100 μm to 220 μm; imparting a lubricant to the at least one surface of the metallic ingot; and subjecting the metallic ingot to impact pressing while the surface coated with the lubricant with respect to the metallic ingot is set as a bottom surface, to thereby mold a cylindrical metal member.
