- 1. An isolation transformer comprising primary and secondary cores and primary and secondary coils,wherein said primary coil and said secondary coil are disposed with a gap provided therebetween, wherein each of said primary coil and said secondary coil is formed of a wire having a substantially rectangular cross section with at least two approximately parallel long sides, and a length of said two long sides in each of said wires is set to be longer than a distance between the two long sides in each of said wires, wherein the primary and secondary coils are disposed in a manner such that the long sides of the wire of the primary coil are aligned with the long sides of the wire of the secondary coil, and wherein each of said wires is wound to have a plurality of turns in a manner such that an outer one of said two long sides of each inner one of said turns is adjacent to an inner one of said two long sides of each respective adjacent outer one of said turns.
- 2.
