Abstract

PURPOSE: To provide a method of manufacturing a high-pressure metal vapor discharge lamp, according to which, upon effecting sealing and air-exhausting treatment to a lamp tube having no exhaust tube, an electrode used for sealing the other end is placed at one end of the lamp tube, and it is heated to a high temperature simultaneously with a first sealing treatment, whereby moisture is removed from the electrode so that electric discharge is readily caused in argon gas.
