A coil structure includes: a magnetic core that defines a closed loop magnetic path in which a magnetic flux flows, the magnetic core including a core leg; a coil that is wound around the core leg about a coil axis extending in a first direction, the coil generating the magnetic flux; a detour member that is separate from the magnetic core, the detour member defining a detour magnetic path that detours around the closed loop magnetic path between first and second points, the detour member including a first piece that defines the first point and a second piece that defines the second point; and a fixing portion that includes an adjoining member adjoining the core leg and a connecting portion connecting at least one of the first piece and the second piece to the adjoining member and fixes positional relations among the core leg and the first and second points.
