PROBLEM TO BE SOLVED: To provide a production method of a collected conductor suppressed in decrease of the space factor.SOLUTION: A production method of a collected conductor comprises forming a conductor wire bundle (30) by arranging peripheral conductor wires (10) around a central conductor wire (20), forming a twisted conductor wire bundle (31) by compression-forming the conductor wire bundle (30) after the twisting and providing an insulation layer on the outer peripheral surface of the resultant twisted conductor wire bundle (31). The peripheral conductor wires (10) have a polygonal cross section. The corner parts (1a, 1b, 1c and 1d) of the cross section of the peripheral conductor wires (10) include outer peripheral corner parts (1a and 1b) arranged on the outer periphery of the conductor wire bundle (30), and the outer peripheral corner parts (1a and 1b) are R-shaped.SELECTED DRAWING: Figure 3 |
