PROBLEM TO BE SOLVED: To provide a welding stud capable of suitably welding a thin panel even when the thin panel is a member to be welded. SOLUTION: The welding stud 10 has a welding flange 11 welded to the member to be welded and a portion 13 to be integrally formed with the welding flange. In the welding flange 11, the outer peripheral portion of the surface at a side to be welded is evenly formed in an annular portion 14 having a certain width and a conical recessed portion 15 is formed from the annular portion 14 toward the center. Therefore only the annular portion 14 is welded to the member to be welded. COPYRIGHT: (C)2009,JPO&INPIT
