ELEMENT WIRE ASSEMBLY AND METHOD FOR MANUFACTURING THE SAME

摘要

A method for manufacturing an element wire assembly includes: a first step of bunching up and rolling or drawing a plurality of circular cross-section conducting wires (1) to shape each of the conducting wires into a polygon in cross section and form the conducting wires (1') and form a conducting wire assembly (10); and a second step of heat-treating the conducting wire assembly (10) to form an oxide film (2) on the periphery of each of the conducting wires (Γ) to form element wires (3) and form an element wire assembly (20).
