Beschreibung
Zusammenfassung:	An adhesion-resistant oxygen-free copper roughly drawn wire not being adhered to each other and being mass-produced at low cost is provided. The adhesion-resistant oxygen-free copper roughly drawn wire (1) contains oxygen in concentration of 1 to 10 ppm and hydrogen in concentration of 1 ppm or less and having a gross oxidation film (5) 50 to 500 angstroms in thickness with an oxidation film of Cu2O (7) being present in a part of said gross oxidation film (5).
