Abstract: For stably supplying an electron emitting substance and preventing illuminance fluctuations, a cathode is provided made from a tungsten material containing an electron emitting substance and having a taper part a diameter of which becomes smaller towards a tip end, a tip end face formed at the tip end side of said taper part, and a fine hole extending from said tip end face in an interior of said cathode, wherein said fine hole is formed at said tip end face such that it extends over at least two tungsten crystal grains. The invention also relates to a short arc type discharge lamp comprising said cathode.

Abstract: A discharge lamp has an electrode comprising a base portion having a base portion side flange portion, and a lid portion having a lid portion side flange portion. In a sealed space of the electrode, heat conductive member is enclosed. At time of lighting, the electrode is not damaged, and the discharge lamp can be stably operated. In the electrode, the diameter direction width of a welding portion of a base portion side flat portion and a lid portion side flat portion is 0.8 to 3.0. Further, an angle formed by the base portion side flat portion and a base side slope portion is 30 degrees or less and an angle formed by the lid portion side flat portion and a lid side slope portion is 30 degrees or less. The sum total of these angle is 160 degrees or less.
