PROBLEM TO BE SOLVED: To provide an electromagnetic induction spiral inductor, in which inductance efficiency per unit volume can be enhanced, by generating electromagnetic induction, which is generated by the fluctuations of current, not only in one direction but also in multiple directions. SOLUTION: A wiring layer of a spiral inductor conductor is divided into two. A divided wiring layer 21 of the spiral inductor conductor and a divided wiring layer 22 of the spiral inductor conductor are formed on an insulating substrate 11 via an insulating layer 12. The divided wiring layer 21 of the spiral inductor conductor and the divided wiring layer 22 of the spiral inductor conductor are electrically connected by a via 41. The electromagnetic induction spiral inductor with a two-layer structure, in which the divided wiring layer 21 of the spiral inductor conductor and the divided wiring layer 22 of the spiral inductor conductor move in and out via the insulating layer 12, can be obtained.
