ABSTRACT:
A high pressure discharge lamp includes a quartz glass bulb and a pair of electrodes. Each electrode of the pair of electrodes is disposed so as to be opposite the other in the quartz glass bulb. The quartz glass bulb of the high pressure discharge lamp contains at least mercury and a halogen gas which are airtightly sealed in the quartz glass bulb. The partial pressure of oxygen (O) in the quartz glass bulb is about 2.5×10−3Pa or less and the partial pressure of the halogen gas in the quartz glass bulb is in the range between about 1×10−6μmol/mm3and 1×10−8μmol/mm3. The pair of electrodes contain potassium oxide in the range between about 20 ppm and 40 ppm.
