PROBLEM TO BE SOLVED: To provide a fixing structure for a welding electrode and a welding head capable of enhancing the durability of the welding electrode, enhancing the work efficiency in welding, reducing the changing time, and executing the welding for a long time with high reliability. SOLUTION: A fixed section 305 of a welding electrode 301 is inserted via a thermally conductive material 303 into an inserting section 304 of a fixing base 302 having the inserting section 304 for inserting the welding electrode 301. A peripheral surface of the fixed section 305 of the welding electrode 301 is uniformly contacted to the fixing base 302 to fix the welding electrode 301 to the fixing base 304.
