For manufacturing a high-pressure discharge lamp, a tungsten electrode is welded to a molybdenum foil by bringing a shaft of tungsten electrode into close contact with the molybdenum foil, and by irradiating a laser light, having a metal melting wavelength, to a junction of the molybdenum foil with the tungsten electrode from a location closer to the molybdenum foil to melt both the molybdenum foil and the shaft of the tungsten electrode for bonding.
