PRODUCTION METHOD FOR MOLTEN-ALUMINUM-PLATED COPPER WIRE

A production method for a molten-aluminum-plated copper wire is disclosed. The method is characterized in that a copper wire (2) immersion part (6) at which the copper wire (2) is to be immersed in amolten aluminum plating bath (1) is immersed in the molten aluminum plating bath (1) after the copper wire (2) has been passed into a copper wire introduction device (7) while an immersion region (9a)thereof has been immersed in the molten aluminum plating bath (1); the copper wire introduction device (7) comprises a tube-shaped body (9), which has a total length of 10-1000 mm and has a through hole (8) that is for passing the copper wire (2) through the inside thereof, and includes the immersion region (9a), which is for immersion in the molten aluminum plating bath (1) to a length of 2-400mm from an end part of one end of the tube-shaped body (9) along the long direction of the tube-shaped body (9); the ratio of the area of the opening of the through hole (8) and the area of a horizontal cross-section of the cop
