摘要
PROBLEM TO BE SOLVED: To provide a resistance-welding electrode which can be easily manufactured and is compact, and whose service life can be made longer, and which enables welding work in a limited narrow space, and to provide a using method of the resistance-welding electrode, a manufacturing method of the resistance-welding electrode, a resistance-welding method, and a resistance-welding device.;SOLUTION: In a main electrode 67 and a sub-electrode 57, its electrode body is a polygonal column of a cross-sectional octagonal shape when viewed from the central axis O direction, and respective eight flat surfaces formed at an equal pitch in the circumferential direction around the central axis O, become first-eighth contact surfaces f1-f8 for welding a welding object member, respectively.;COPYRIGHT: (C)2014,JPO&INPIT
