ABSTRACT:
A low-pressure discharge lamp having a tubular glass lamp vessel10, on an outer surface of which conductor layers are formed as electrodes21and26. The ultrasonic solder dipping layers31and36are formed at both ends of the vessel10as conductor layers. The end surfaces of the glass lamp vessel are blasted and ultrasonic solder dipping layers are formed on the blasted surfaces41and46by ultrasonic solder dipping. Conductor layers form external electrodes21and26, which are in contact with the glass surface more strongly. A low-pressure discharge lamp having the conductor layers of a uniform thickness can be mass-produced at low cost.
