Abstract
Before an electrode assembly is inserted into a quartz glass tube, a reinforcement bending process is applied to a metal foil. Even when a vibration load acts on the electrode assembly during the insertion of the electrode assembly into the quartz glass tube, the metal foil is not easily deformed, so that a rod electrode can be prevented from largely swinging together with the metal foil. Consequently, the position of a tip end portion of the rod electrode can be easily recognized by using a camera, whereby the degree of the insertion of the electrode assembly into the quartz glass tube can be correctly adjusted.
