PROBLEM TO BE SOLVED: To reduce stresses at mounting on teeth, by facilitating coupling between coils. SOLUTION: A pair of ends of a conductor are drawn out of the end face of a molded-coil 3. The ends of the conductors drawn out of the molded coil 3, which adjoin each other when mounted on a teeth are connected with each other by means of conductive connecting metal fitting 20. For the connecting metal fitting 20, joint 21 connectable with the end of the conductors are arranged at both ends, and spring 22 having spring property is arranged in the middle. When mounting a coil unit 12 mode of coupled molded coils 3 to the teeth, the twisting force or the like acts on the connecting metal fitting 20, but the stress is reduced by the spring 22, and this results in no excessive force acting between the connection and the conductor.
