PROBLEM TO BE SOLVED: To provide an air-core coil which is hard to roll and very stable and has a lead structure that prevents its soldered parts from having an adverse effect on magnetic properties. SOLUTION: In an air-core coil 40, leads 45, 46 of both ends of the winding of an air-core coil on which conductor is wound like a tube, are bent near the peripheral face 7 of the body 4 of the air-core coil, and are generally parallel to the axis J of the coil winding. Moreover, the leads 45, 46 are positioned below the lower end 7a of the body 4 of the air-core coil, and the distance between the leads is larger than the diameterϕof the air-core coil body 4 (a constitution having its legs 43, 44 spreading downward away from each other).
