PROBLEM TO BE SOLVED: To facilitate a repair of the disconnection of the conductor pattern of a printed circuit board and raise the quality of the repair in a repairing material supply mechanism for supplying and holding a repairing material to a repair location when any disconnection is repaired. SOLUTION: The repairing material supply mechanism comprises a feeding pipe 7 for feeding out the repairing material 4 and a suction pipe 9 provided substantially opposing the foregoing pipe. The repairing material 4 is fed out from the feeding pipe 7 by the drive of a feeding part 6, and the repairing material 4 thus fed out is sucked into the suction pipe 9. The repairing material 4 is welded to conductor patterns on opposite sides of a disconnection portion by applying the repairing material 4, opposite sides of which are held as described above, to the disconnection portion and supplying electric power thereto while bringing a welding electrode 5 from an upper portion.
