In FIG. 7A, the pad with reference numeral 1 corresponds to the first pin 21, the pad with reference numeral 2 corresponds to the second pin 22, and the pad with reference numeral 3 corresponds to the third pin 31. The pad with reference numeral 4 corresponds to the fourth pin 32, the pad with reference numeral 5 corresponds to the fifth pin 41, and the pad with reference numeral 6 corresponds to the sixth pin 42. Therefore, in the pad layout on the PCB circuit board, the second pin 22 and the third pin 31 are connected, and the fourth pin 32 and the fifth pin 41 are connected.

On the other hand, the pad layout of FIG. 7A corresponds to the plurality of pins shown in FIGS. 1, 2, 3 and 4C and the slope corresponding to the plurality of pins. Since the first slope 21a and the third slope 31a are opposite surfaces, and the third slope 31a and the fifth slope 41a are in the same direction, the distance between the pad of reference numeral 1 and the pad of reference numeral 3 Is wide, and the distance between the pad of reference numeral 3 and the pad of reference numeral 5 is narrow. However, the embodiment of FIG. 4D is adopted, and the directions of the first slope 21a, the second slope 22a, the third slope 31a, the fourth slope 32a, the fifth slope 41a, and the sixth slope 42a are all all directions. If they are the same, the distance between the pad of reference numeral 1 and the pad of reference numeral 3 will be the same as the distance between the pad of reference numeral 3 and the pad of reference numeral 5.

See FIG. 8A. FIG. 8A is a circuit diagram corresponding to the case where the magnetic device 10 of the present invention is arranged in the circuit layout corresponding to FIG. 7A.

Then, as in the embodiment, the three coils of the magnetic element 14 are connected in series, that is, the magnetic device 10 of the present invention forms the circuit characteristics shown in FIG. 8A by the circuit layout of FIG.

As shown in FIGS. 7B and 8B, in FIG. 7B, by connecting the pads of reference numerals 1, 3, and 5 and the pads of reference numerals 2, 4, and 6, the magnetic device 10 of the present invention can be used.
