Abstract
The coil manufacturing apparatus includes: a bending device configured to bend each of a plurality of flat conductors; and a welding device configured to weld the plurality of flat conductors. The bending device is a unit configured to bend each of the flat conductors before being supplied to the welding device. The welding device includes a first holding portion and a second holding portion disposed facing each other, and a driving portion configured to move the first holding portion and the second holding portion. The helical structure body is formed by pressing end faces of the one flat conductor and the another flat conductor against each other along a strip longitudinal direction and joining the flat conductors through pressure welding while reducing a distance in the strip longitudinal direction. The coil manufacturing apparatus includes a removing device configured to remove an unwanted portion of the flat conductors generated by welding.
