PROBLEM TO BE SOLVED: To provide a drawing stock of copper or a copper alloy which is hard to be scratched when the drawing stock is wound and the wound drawing stock is delivered and excellent in handleability in the wound state. SOLUTION: The drawing stock of the copper or the copper alloy has an oil content quantity of 0.5-50μg/cm<SP>2</SP>on the wire surface. When the oil content quantity on the surface of the drawing stock is small, the sliding property of the wire surface is insufficient and the wire surface is scratched when the drawing stock is wound and the wound drawing stock is delivered. When the wire surface has much oil content quantity, the drawing stock is apt to cause load collapse in the wound state and the handleability is bad during the storage and conveyance.
