Abstract
A 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, including: transferring a linear waver conductor shaped in a substantially rectangular waveform, and having straight side portions extending in a wave width direction, one-side connecting portions sequentially connecting every other pair of adjacent side portions at ends on a one wave width direction side, and other-side connecting portions sequentially connecting pairs of adjacent side portions that are not connected by the one-side connecting portions at ends on an other wave width direction side; bending a target connecting portion, which is at least one of the one-side connecting portions and the other-side connecting portions of the wave conductor, at one position thereof to shape the target connecting portion into a substantially V shape so that the side portions are arranged along a coil circumferential direction and directions of cross-sectional shapes of the side portions are in a constant direction with respect to a coil radial direction; and winding the bent wave conductor on a bobbin.
