Coil for electrical and electronic equipment as well as process for production thereof

摘要

A coil for electrical and electronic equipment comprises a spiral conductor coil 2 prepared by disposing coaxially a plurality of conductors 4a through 4d each having a flat circular arc-shaped configuration in multiple stages along a vertical direction, and linking sequentially ends of these conductors 4a through 4d to each other by means of linking members 5a through 5c in the vertical direction; and an insulating layer 3 covering the surface of the conductor coil 2, so that a relationship between a conductor width and a coil core diameter does not depend mutually, it becomes possible to increase and decrease optionally the conductor width and the coil core diameter, and as a result, a wider conductor width and a smaller coil core diameter in the conductor coil 2 than that of a conventional coil can be achieved.
