Abstract
The high-pressure discharge lamp includes: a pre-seal glass inserted in the internal space of each of seal portions and integrally comprising a metal foil sheathing portion which sheathes a metal foil, an electrode sheathing portion which sheathes a portion of an electrode that extends from a first end of the metal foil toward a base portion and an external lead pin sheathing portion which sheathes a portion of an external lead pin that extends outwardly from the other end of the metal foil; and a conductor for generating discharge between the conductor and the metal foil. The electrode sheathing portion is fused to the base portion. The external lead pin sheathing portion has an outer surface hermetically fused to an inner surface of one of the seal portions. A clearance hermetically sealed between the pre-seal glass and the seal portion encapsulates inert gas therein.
