<P>PROBLEM TO BE SOLVED: To provide a coil manufacturing method and the like capable of properly manufacturing a wave wound coil in a substantially cylindrical shape in which linear conductors are aligned and arranged by sequentially shaping the linear conductor with a cross-sectional shape having directionality. <P>SOLUTION: The coil manufacturing method for manufacturing a wave wound coil in a substantially cylindrical shape by shaping a linear conductor with a cross-sectional shape having directionality, includes: a transfer step Pf for transferring a wave conductor as a linear conductor shaped in a substantially rectangular waveform, and having straight side portions extending in a wave width direction, one side connecting portions and other side connection portions for sequentially connecting every other pair of two side portions at respective one side and the other side in a wave width direction; a first bending step P5 and a second bending step P6 for bending the one side and the other side connection portions so that the side portions may be arranged along a coil circumferential direction, and the directions of cross-sectional shapes of the side portions may be in a fixed direction with respect to a coil radial direction; and a winding step P7 for winding the wave conductor subjected to bending processing in these steps on a bobbin. <P>COPYRIGHT: (C)2010,JPO&INPIT |
