PROBLEM TO BE SOLVED: To enable to mass-produce low-pressure discharge lamps having a uniform thickness of a current conductive layer of an external electrode by lowering price. SOLUTION: The low-pressure discharge lamp 11 is equipped with a tubular glass lamp container 10 with current conductive layers 31, 36 formed as electrodes on an external surface, the current conductive layer is an ultrasonic solder dipping layer formed by ultrasonic solder dipping.
