Abstract
An electrode module includes an electrode and a core wire inserted into a core wire insertion hole of the electrode. When inserting the core wire into the core wire insertion hole of the electrode, the core wire can be inserted smoothly, thereby avoiding occurrence of chipping or cracking in the core wire insertion hole. A low-friction layer is provided on the inner surface of the core wire insertion hole of the electrode and/or the outer periphery of the inserted portion of the core wire.
