COIL, AND METHOD AND APPARATUS FOR MANUFACTURE THEREOF

摘要

Coils are provided which can be closely arranged in series along their axes without gaps between them. A coil (20) includes one conductor (2) consisting of a first conductor part (2A) and a second conductor part (2B), which are sectioned at a predetermined position (2C). The first conductor (2A) is wound from the part (2c) from the axis to form a first coil of a predetermined width, while the second conductor (2B) is wound from the part (2c) in the direction opposite to the first coil (20A) to form a second coil (20B) that is narrower than the predetermined width. Two ends (21, 22) are exposed outside to serve as the coil terminals. Since the terminals of the coil are both positioned outside, they will not cause interference when a number of coils (20) are closely arranged in the axial direction.
