Abstract: PROBLEM TO BE SOLVED: To provide an inexpensive casting material by a continuous casting method (up casting process), to provide a copper wire for a magnet wire obtained by subjecting the same to wire drawing, and to provide a magnet wire. SOLUTION: Regarding the casting material produced by performing continuous pulling-up from the molten metal of copper and a copper alloy through a casting die, the crystal size of the crystal structure of the casting material 22 is 200 to 300 μm, and also, the crystal size to a depth of 500 μm from the surface is 20 to 200 μm. The copper wire 2 for a magnet wire uses the same, and a magnet wire 1 is obtained therefrom. COPYRIGHT: (C)2010,JPO&INPIT
