A stainless steel substrate with one or more conductive metal layers, a method for manufacturing the same, and a hard disk drive suspension material using the same that are excellent in etching accuracy and does not involve the use of any substances casing environmental burdens, while ensuring stable adhesion between the conductive metal layers on the stainless steel substrate and the polyimide-based resin layer. The conductive metal layers are formed to have a total thickness ranging from 0.1 to 10 ?m, a centerline average surface roughness Ra from 0.05 to 1 ?m, and a ten-point average surface roughness Rz from 1 to 5 ?m, respectively.

摘要:
An ultrathin stainless steel foil of a thickness of 25 &mgr;m or less whose average number of inclusions of a major diameter of 5 &mgr;m or greater per 1 mm2 in sections along the rolling direction is 3 or less. The ultrathin stainless steel foil is not readily susceptible to the local tunnel-like corrosions (voids) that have occasionally occurred, during etching, together with cracking in the rolling direction from the edges.
