Abstract

PURPOSE: To establish the glass hollow body lower in the discharge start voltage and representing stable performance for a long time, by conducting the smoking attaching processings of metal oxide twice, inside the glass tube.
CONSTITUTION: Venting toward the one end 5b from another end 5a is made in the glass tube 5 having sufficiently greater diameter than that of glass hollow body finally obtained as shown in the arrow a. With this condition, near the end 5a of the tube 5, the metal material (e.g. Mg) being the constituent of the metal oxide forming the protective film is burned, and the burned smoke flow (MgO) flows in the tube 5 and the metal oxide 9 is coated inside the tube. Further, the tube 5 coated with the metal oxide 9 is extended with the heating furnace 10 and the roller 11 to obtain the tube 12 of small diameter. To this tube 12, the smoking attaching processing is made to form the protective film 13.
