A multilayered device comprising: a first insulation sheet having at least two foldable areas (11, 12,...) 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 area (111, 112...) which are multilayered by being folded; wherein a first conductor (21A, 22A...) is formed on a first face (11A, 12A...) and constitutes a first coil having one turn or more, and a second conductor (21B, 22B...) is formed on a second face (11B, 12B...) and constitutes a second coil having one turn or more in the same winding direction as that of the first coil in each of the foldable areas of the first insulation sheet; a third conductor (121A, 122A...) is formed on a first face (111A, 112A...) and constitute a third coil having one turn or more and a fourth conductor (121B, 122B...) is formed on a second face (121B, 122B...) and constitutes a fourth coil having one turn or more in the same winding direction as that of the third coil in each foldable area of the second insulation sheet; a first inductor is constituted so that an end of the first conductor on the first face of the foldable area of the first insulation sheet and an end of the third conductor on the first face of the foldable area of the second insulation sheet corresponding to the foldable area are conducted through a first via hole (3A: 131, 132...) formed to penetrate through the first insulation sheet; a second inductor is constituted so that an end of the second conductor on the second face of the foldable area of the first insulation sheet and an end of the fourth conductor on the second face of the foldable area of the second insulation sheet corresponding to the foldable area are conducted through a second via hole (3B: 141, 142...) formed to penetrate through the second insulation sheet; and a capacitor of distributed constant is constituted between a conductor configured by the first conductor and the third conductor and a conductor configured by the second conductor and the fourth conductor. a first insulation sheet having at least two foldable areas (11, 12,...) 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 area (111, 112...) which are multilayered by being folded; wherein a first conductor (21A, 22A...) is formed on a first face (11A, 12A...) and constitutes a first coil having one turn or more, and a second conductor (21B, 22B...) is formed on a second face (11B, 12B...) and constitutes a second coil having one turn or more in the same winding direction as that of the first coil in each of the foldable areas of the first insulation sheet; a third conductor (121A, 122A...) is formed on a first face (111A, 112A...) and constitute a third coil having one turn or more and a fourth conductor (121B, 122B...) is formed on a second face (121B, 122B...) and constitutes a fourth coil having one turn or more in the same winding direction as that of the third coil in each foldable area of the second insulation sheet; a first inductor is constituted so that an end of the first conductor on the first face of the foldable area of the first insulation sheet and an end of the third conductor on the first face of the foldable area of the second insulation sheet corresponding to the foldable area are conducted through a first via hole (3A: 131, 132...) formed to penetrate through the first insulation sheet; a second inductor is constituted so that an end of the second conductor on the second face of the foldable area of the first insulation sheet and an end of the fourth conductor on the second face of the foldable area of the second insulation sheet corresponding to the foldable area are conducted through a second via hole (3B: 141, 142...) formed to penetrate through the second insulation sheet; and
