Pressing the outer peripheral surface of the silver oxide wire with a certain pressure while rotating in the same direction as each other,
In addition, the outer periphery of the silver oxide wire is polished while revolving around the silver oxide wire.

10μｍであった。(Example) An example of the method for polishing a silver oxide wire rod of the present invention is described as follows.
Explaining with reference to the figure, a pair of rotary grindstones 5 and 5 'made of silicon carbide having a diameter of 355 mm and a thickness of 50 mm 5.
In a gap 6 of 5mm, a wire 2 of Ag-CdO12%
min, and the outer circumference of the wire 2 is pressed at 2.0 kg / cm 2 while rotating the pair of rotating grindstones 5 and 5 ′ in the same direction at 1,000 rpm, and the wire 2 is centered as shown by the arrow.
After revolving at 100 rpm and polishing the outer peripheral surface of the wire 2, the adhered material was removed without breaking, and the surface roughness of the outer peripheral surface was
It was 10 μm.
