<p>PURPOSE:To omit an insulation treatment of a transformer, a coil, a primary coil and a secondary coil, to make the transformer sharply small-sized, to enhance the productivity of the transformer by an automatic coil winding operation and to lower its costs by a method wherein an insulating electric wire itself is provided with the interlayer insulating function and the creeping insulation distance function between the primary coil and the secondary coil which are formed separately from the coil at the transformer. CONSTITUTION:The following can be obtained: an insulating electric wire 12, for high-frequency transformer use, in which extruded coating insulating layers 12d, 12f have been formed, via mold-releasing layers 12c, 12e, on an insulating electric wire provided with an insulating layer 12b on a conductor 12a; and a transformer for high-frequency which uses the electric wire as a coil wire material.</p> |
