Document Type and Number:
WIPO Patent Application WO/2020/195319
Kind Code:
A1
Abstract:
An insulated copper wire (10) comprises a copper wire and an insulating coating (12) that covers the surface of the copper wire, wherein: the insulating coating (12) includes a polymeric material with amide bonds; at a stripped surface (14) formed on the surface of the insulated copper wire by peeling away the insulating coating (12), copper atoms bonded with nitrogen atoms or carbon atoms are more abundant than copper atoms bonded with oxygen atoms; and an oxygen-containing layer (13) that contains at least 10 at% oxygen is formed from the stripped surface (14) in the depth direction, with the thickness of the oxygen-containing layer (13) being in the range of 2-30 nm. An electric coil is formed by winding the insulated copper wire (10).
