PROBLEM TO BE SOLVED: To provide a manufacturing method which enables a shortening of the rolling start time of a rolling machine without complicating the device configuration, an increase in precision of thickness and width of a flat conductor, and an increase in precision and a uniformity over the full length of the flat conductor.SOLUTION: As a bearing part 22 that supports pressure rolls 21 so as to be rotatable and a support part 23 that supports the bearing part remain preheated with preheating means, a round conductor 100 is made to pass between the pressure rolls 21 to be worked into a flat conductor 101. The preheating means can be exemplified by external heating means or internal friction heat means. The external heating means indicates preheating the bearing part and the support part of a rolling machine 20 from outside (using another configuration), and the internal friction heat means indicates preheating the bearing part and the support part of the rolling machine with a friction heat accompanying roll rotation between an outer peripheral surface of a roll shaft 21a and an inner peripheral surface of the bearing part. |
