摘要： A stamper-forming electrode material contains Ag as its main ingredient and at least one other element, preferably Au and/or Cu. It is preferred that the Au and Cu contents each be 5.0 wt % or less. A stamper-forming thin film is made of this stamper-forming electrode material, whereby its corrosion resistance is improved to suppress damage to itself, and a high-quality stamper can hence be formed.

No data is recorded on the guard areas.
