The purpose of this invention is to provide a method that is used to manufacture a wound electronic component using twisted wires and makes it possible, when twisting a plurality of winding wires together, to minimize breakage thereof. This method for manufacturing a wound electronic component (1) includes a preparation step in which a chuck (C1) is used to grip a core (12) that has a winding-core section (14) and flanges (16 and 18), a first step in which part of each of a number of winding wires (20, 21) supplied from respective nozzles (N1, N2) is affixed to one of the flanges (16), and a second step in which the chuck (C1) is rotated so as to twist the winding wires (20, 21).
