A coil device is provided which has a small loss in a high-frequency band even if it has an air core or a core material used is not of so high quality when it has a core, generates little magnetic extraneous radiation, has a stable frequency characteristic of an inductance, and can be manufactured at low cost. What is formed by winding a linear conductor around two axes which are parallel with each other to be in a substantially S-shape as a whole by one turn with winding directions made different is set as one layer of unit winding, the unit windings are stacked in a plurality of layers while aligning the axes, and the unit windings of all layers are electrically connected in series.
