Beschreibung
Zusammenfassung:	A coil device includes a bobbin (20), A first winding part (30), and a second winding part (40). A partition portion (28) is formed on an outer peripheral surface (22) of the bobbin. The first winding part is wound around the outer peripheral surface at one side of the partition portion. The second winding part is wound around the outer peripheral surface at the other side of the partition portion and has an inner winding layer and an outer winding layer located farther to the outer peripheral surface at the other side than the inner winding layer. The second winding part has a first wire winding part (42) and a second winding part (44). In the inner winding layer, one of the first wire winding part (42) and the second winding part (44) is more close to the first winding part (30) than the other one; and in the outer winding layer, the other one of the first wire winding part (42) and the second winding part (44) is more close to the first winding part (30) than one. 本发明提供种线圈装置，其具有：骨架(20)，其在外周面(22)具有分隔部(28)；第
