Abstract: A method for producing a coil for electric apparatus of the present invention is the method for producing a coil for electric apparatus for cutting spirally a block-shaped workpiece formed with a cylindrical portion corresponding to the coil in a circumferential direction of the cylindrical portion, the spiral coil is formed by turning a cutting means while moving it relatively to the workpiece from a part corresponding to one end of the coil to a part corresponding the other end of the coil along a machining line spirally set in the circumferential direction of the cylindrical portion. According to the invention, since the coil is formed by cutting the continuous cutting machining plane without generating a step in design from the block-shaped workpiece formed with a cylindrical portion corresponding to the coil using a wire-tool etc., it is possible to constitute a high-quality coil.

Abstract: A coil includes a first coil layer and a second coil layer which is formed by winding a rectangular conductor. A side surface of the second coil layer contacts a side surface of the first coil layer in a second direction that is perpendicular to a radial first direction where the rectangular conductor overlaps. In the first coil layer, a second portion contacts a first portion. In the second coil layer, a fourth portion contacts a third portion. An outer surface of the third portion is closer to an outer peripheral side in the first direction than the outer surface of the first portion, and is closer to an inner peripheral side in the first direction than an outer surface of the second portion. An outer surface of the fourth portion is closer to the outer peripheral side in the first direction than the outer surface of the second portion.
