摘要： A method for manufacturing a discharge tube, including heating a quartz tube by irradiation and closing it shut, is presented, in which variation of the heating temperature of the quartz tube can be reduced. Laser light is irradiated on a portion of the quartz tube, and in the step of sealing the portion of the quartz tube onto which laser light has been irradiated, the laser light is scanned while oscillating back and forth. The intensity of the laser light is controlled such that the intensity of the laser light when the size of a displacement of the laser light is maximal is smaller than the intensity of the laser light when the size of the displacement of the laser light is minimal.

摘要： In a method for manufacturing a discharge tube including a discharge part, a sealing part formed at an end of the discharge part, and an electrode provided in the discharge part, the method includes inserting an electrode body having the electrode into a portion to be the sealing part that is adjacent to a portion to be the discharge part of a transparent insulating tube serving as a material for the discharge tube, and then sealing the portion to be the sealing part by heating and softening with a combination of a laser beam and a gas burner, thus forming the sealing part. Heat sources are selected suitably according to each region in the portion to be the sealing part, whereby a high-quality discharge tube that is highly resistant to pressure can be manufactured at high production efficiency and low cost.
