PROBLEM TO BE SOLVED: To improve luminance by suppressing spread of a spot in a cathode.;SOLUTION: In the DC short-arc discharge lamp, tungsten substantially free from easily electron emitting material is used as an electrode material of the cathode 11. According to this, the spread of the spot in the cathode 11 can be suppressed, and improvement in luminance can be attained.;COPYRIGHT: (C)2010,JPO&INPIT
