摘要：
A high pressure discharge lamp has a sealing portion that is made of glass and a sealing metal piece. In a method of manufacturing the high pressure discharge lamp, the sealing metal piece is irradiated with laser beam whose pulse width is 1×10−9 seconds or less, so as to carry out a surface treatment of the sealing metal piece. The sealing metal piece may have a groove that is 120 to 600 nm in depth and 450 to 1,200 nm in width.
