<p>PROBLEM TO BE SOLVED: To provide a multifunction sheet capable of reducing the height of an inductor and a transformer circuit, and in which other components are integrated into one body.SOLUTION: Coil-like wiring patterns 7, 7are formed on surfaces of first insulation sheet 1and second insulation sheet 1provided with slits 2, 2, respectively, and coil-like wiring patterns of the same shape are formed on the reverse sides. Then, by engaging the slits 2, 2with each other, the coil-like wiring pattern 7and the coil-like wiring pattern on the reverse side of the second insulation sheet 1are connected to constitute a first coil-like wiring element, and the coil-like wiring pattern 7and the coil-like wiring pattern on the reverse side of the second insulation sheet 1are connected to constitute a second coil-like wiring element. Thus, a double helical structure coil-like wiring is formed by stacking these wiring elements one on top of another in the stacking direction across an insulator.</p> |
