PROBLEM TO BE SOLVED: To provide a coil device that has a high space factor and saves space.SOLUTION: A coil device comprises: a bobbin (20) having a partition part (28) on its outer periphery (22); a first coil part (30) wound around an outer periphery (22a) on one side of the partition part; and a second coil part (40) wound around an outer periphery (22b) on the other side of the partition part and having an inner coil layer (40a) and an outer coil layer (40b) located further from the outer periphery on the other side than the inner coil layer. The second coil part has a first wire part (42) and a second wire part (44) wound so as to be adjacent to each other in the direction of a winding shaft. In the inner coil part, one of the first wire part and the second wire part is disposed nearer to the first coil part than the other. In the outer coil part, the other of the first wire part and the second wire part is disposed nearer to the first coil part than the one.SELECTED DRAWING: Figure 1 |
