PROBLEM TO BE SOLVED: To provide a technique which can implement high design flexibility concerning occurrence position of leakage inductance and easily adjust the magnitude of the leakage inductance.SOLUTION: A coil structure 100 has a magnetic core 200 forming a closed loop CLP in which a magnetic flux flows, a coil portion 300 which surrounds a coil axis CA extending in a first direction and generates a magnetic flux, a bypass member 400 which is formed separately from the magnetic core and bypasses a part of the magnetic flux flowing in the closed loop, and a fixing portion 500 for fixing the bypass member. The magnetic core contains a core leg 210 inserted in the coil portion. The bypass member defines a bypass magnetic path DMP for bypassing the closed loop. The fixing portion fixes the first positional relationship between the core leg and a first point, and the second positional relationship between the core leg and a second point. The bypass member contains a first piece defining the first point and a second piece defining the second point. The fixing portion contains an adjacent member disposed adjacently to the core leg, and a connection portion for connecting the first piece and the second piece to the adjacent member. |
