Abstract:
In an odd number of three or more layers (L1-L3) of a substrate (3), a coil pattern (4a-4c) is wound a plurality of times in the same direction around an opening section (3m) into which a core (2a) is inserted. In the first layer (L1) on the front surface side of the substrate (3), the coil pattern (4a) is wound inward; in the second layer (L2), the coil pattern (4b) is wound outward; and in the third layer (L3) on the back surface side of the substrate (3), the coil pattern (4c) is wound outward. The inner end (4a2) of the coil pattern (4a) and the inner end (4b2) of the coil pattern (4b) are connected via a through hole (9a), and the outer end (4b1) of the coil pattern (4b) and the inner end (4c2) of the coil pattern (4c) are connected via a through hole (9b). The outer end (4a1) of the coil pattern (4a) is connected to one terminal (6o) for power input and output, and the outer end (4c1) of the coil pattern (4c) is connected to the other terminal (6i).
