Abstract:
1. A multilayered device comprising: a first insulation sheet having at least two foldable areas which are multilayered by being folded; and a second insulation sheet which is provided in parallel with the first insulation sheet, and has at least two foldable areas which are multilayered by being folded, wherein each of the foldable areas of the first insulation sheet includes a first conductor which is formed on a first face of the first insulation sheet and constitutes a first coil having one turn or more, and a second conductor which is formed on a second face of the first insulation sheet and constitutes a second coil having one turn or more in the same winding direction as that of the first coil, each of the foldable areas of the second insulation sheet includes a third conductor which is formed on a first face of the second insulation sheet and constitutes a third coil having one turn or more, and a fourth conductor which is formed on a second face of the second insulation sheet and constitutes a fourth coil having one turn or more in the same winding direction as that of the third coil, an end of the first conductor on the first face of each of the foldable areas of the first insulation sheet is connected to an end of the third conductor on the first face of a corresponding foldable area of the second insulation sheet through a first via hole formed to penetrate through the first insulation sheet so as to constitute an inductor; an end of the second conductor on the second face of each of the foldable areas of the first insulation sheet is connected to an end of the fourth conductor on the second face of a corresponding foldable area of the second insulation sheet through a second via hole formed to penetrate through the second insulation sheet so as to constitute an inductor; and a capacitor having a distributed constant is between a conductor formed by the first conductor and the third conductor and a conductor formed by the second conductor and the fourth conductor, and at least four conductors are disposed in parallel with each other by folding the first insulation sheet so as to constitute an inductor.
