摘要：
The present invention aims to prevent breakage of a sealing part and an electrode of a high pressure discharge lamp, and provides an electrode 100 used for a discharge lamp and having a rod-shaped part 101, one end of the rod-shaped part 101 to be sealed by a sealing part of an arc tube of the discharge lamp, the other end of the rod-shaped part 101 to be in a discharge space in the arc tube, wherein the rod-shaped part 101 has a rough surface that is composed of a plurality of types of crystal grains each having a different surface condition due to differences in crystal orientation.
