Title: ELECTRODE TIP
Abstract:
The present invention provides an electrode tip with which cooling efficiency can be improved, and with which a pressurization withstanding performance enabling the electrode tip to withstand pressurization during welding can be improved. An electrode tip 20 is provided with: an electrode tip main body portion 21; and a support post portion 31 which is disposed inside the electrode tip main body portion 21, and abuts a reverse surface 23 side of a distal end portion 22 of the electrode tip main body portion 21 at least during welding pressurization, to thereby suppress displacement of the distal end portion 22 of the electrode tip main body portion 21. The support post portion 31 is formed using a material having higher values of tensile strength and Young's modulus than those of the electrode tip main body portion 21.
