Zusammenfassung:	PURPOSE:To obtain a welding nut, its connection method and a welding nut connecting electrode device which improves shock resistance, dispenses with a positioning pin, and effectively keep a connection condition of the welding nut for a long time. CONSTITUTION:A welding nut 1 is provided with a screw hole 2C, a plurality of welding projections 3 on a periphery of an one end face, and a caulking projection 7 around the screw hole 2c on the side of one end face. In connection of the welding nut 1, the caulking projection 7 is inserted into a caulking hole of a plate, and then caulking of the projection 7 and welding of projections 2, 5 are simultaneously carried out. In respect to a welding nut connecting electrode device, a caulking die is formed on a center of a receiving electrode part opposingly to the caulking projection 7 of the welding nut 1.
