Abstract: The high-pressure discharge lamp of the present invention comprises a light-transmitting ceramic discharge vessel (1), power-supplying conductors (2), a pair of electrodes (3, 3), seals (4) made of ceramic-sealing compound, and a discharge medium. The discharge vessel has an inner volume of 0.1 cc or less. The distal ends of the electrodes are arranged so as to maintain a distance d1 of 1.0 mm or more from the inner surface of the light-transmitting vessel on a plane which is perpendicular to the axis of the light-transmitting vessel and includes the distal ends of the electrodes.
