| abstract | In a discharge lamp in which an emitter other than thorium is added to a cathode in an arc tube, it is possible to prevent the emitter from excessively evaporating from the cathode and deplete at an early stage, and to evaporate the emitter from the side surface of the cathode. Provided is a structure which suppresses white turbidity of the arc tube by suppressing. A main body portion 31 in a cathode 3 is made of a refractory metal material not containing thorium, and a tip portion 32 is made of a refractory metal material containing an emitter (excluding thorium). A sintered body 34 containing an emitter (excluding thorium) having a higher concentration than the emitter concentration contained in the tip portion is embedded in a sealed space formed inside the tip portion and / or the tip portion, The main body part and / or the tip part is characterized in that a fibrous metal structure 5 extending in the axial direction of the cathode is formed in a region around the sintered body.
