Abstract: A method of manufacturing a high-pressure discharge lamp, comprising the steps of: inserting a mount into an interior of a glass tube having an outer diameter smaller than an inner diameter of an end part of a sealed container; radially constricting the glass tube at a first position located away from a metallic foil toward a tip of an electrode; sealing the mount by a region of the glass tube that ranges from the first position to at least the other end of the metallic foil; protruding the electrode out of the glass tube located away from the first position toward the tip of the electrode to form a glass-tube air-tightly sealed mount; inserting the sealed mount into the end part of the sealed container; and radially constricting the end part of the sealed container to sealing the glass tube of the sealed mount by the end part.
