A wire winding apparatus produces a coil of a desired shape quickly and inexpensively. An element wire to be wound on a winding frame is supported while a predetermined tension is applied to the element wire. When the element wire is shifted from a turn to another turn during the winding of the element wire around the winding frame, the element wire is regularly aligned by utilizing the tension applied to the element wire.

1. A wire winding apparatus for forming a coil by winding an element wire, comprising:a rotatable winding frame on which the element wire is wound during rotation of the winding frame; an element wire support that is movable in a direction of a rotation axis of the winding frame, and that supports the element wire and applies a predetermined tension to the element wire; a turn shift portion shaper that contacts the element wire and forms a turn shift portion in the element wire by utilizing the tension applied to the element wire by the element wire support, when the element wire is shifted from a turn to another turn during winding of the element wire around the winding frame; a turn shift portion holder that holds the turn shift portion of the element wire located at a winding starting end of the element wire when the turn shift portion is formed by at least the turn shift portion shaper; and a supporting rotator that supports the turn shift portion shaper and the turn shift portion holder and that is capable of rotating the turn shift portion shaper and the turn shift portion holder about the rotation axis of the winding frame, wherein: the turn shift portion shaper includes a rod-shaped element wire contact portion that contacts the element wire; the turn shift portion holder has a starting end contact portion that contacts the winding starting end; and the turn shift portion shaper and the turn shift portion holder are arranged about the rotation axis of the winding frame, with a predetermined rotational angle formed between the turn shift portion shaper and the turn shift portion holder.
