Claim:
1. An induction device comprising: a first coil formed by winding an insulated conductive wire a plurality of times, the conductive wire being covered with an insulating layer; a second coil being a metallic sheet having a pattern; and a coil support member disposed between the first coil and the second coil, wherein the coil support member is a first insulating substrate, wherein the first coil is supported by the first insulating substrate, wherein a winding start and a winding end of the first coil are connected to the first insulating substrate, wherein the conductive wire forming the first coil is a single continuous wire, wherein the first coil and the second coil are magnetically connected to each other, wherein the first coil is supported by the first insulating substrate and the second coil is supported by a second insulating substrate, wherein a radiator plate, formed of a metal pattern, is supported on one side of the second insulating substrate that is opposite from the second coil and is fixed to a heat sink, and wherein the heat sink, an insulating sheet, the first coil, the first insulating substrate, the second coil, the second insulating substrate and the radiator plate are aligned in an axial direction of the first coil.
