PROBLEM TO BE SOLVED: To provide a lamination type inductor that has less leakage in flux, and can obtain a high inductance. SOLUTION: Each of conductor patterns 23a to 23e for first and second coils that are arranged at the upper section of a laminate and have two-layer structure is electrically connected to conductor patterns 24a to 24f for third and fourth coils that are successively arranged at a lower section and have the two-layer structure in series via a via hole 28 being provided in insulator sheets 22b to 22e, and a spiral coil L is composed. The edge section of the conductor patterns 23a to 23c for the first coil is overlapped to that of the conductor patterns 23d and 23e for the second coil. Similarly, the edge section of the conductor patterns 24d to 24f for the fourth coil is overlapped to that of the conductor patterns 24a and 24c for the third coil.
