PURPOSE: To produce a polishing-finished stainless steel sheet excellent in temper color resistance and to provide its production method. CONSTITUTION: This sheet is a polishing-finished stainless steel sheet excellent in temper color resistance, having a surface oxide film in which the atomic concentration ratio among Cr, Si, Al, and Fe, (Cr+Si+Al)/Fe, in the part between the surface and a position at a depth of 50Åfrom the surface is regulated to >=0.6. This polishing-finished stainless steel sheet excellent in temper color resistance can be produced by subjecting a cold rolled stainless steel sheet to mechanical polishing and then to bright annealing.
