Abstract: The invention relates to a discharge lamp with a discharge vessel of silica glass which has a higher operating pressure than atmospheric pressure, where the high temperature viscosity (VA) in the outer surface area of the arc tube portion of the discharge vessel is lower than the high temperature viscosity (VB) at a depth of 100 microns from the outer surface of the arc tube portion. Since the high temperature viscosity (VA) in the outer surface area of the arc tube portion of the discharge vessel is lower than the high temperature viscosity (VB) at a depth of 100 microns from the outer surface of the arc tube portion, formation of thermal distortion in the vicinity of the outer surface of the arc tube portion can be suppressed. This prevents the discharge vessel from being damaged or from breaking by thermal distortion even after operation for a long time.
