A start assisting light source is configured such that it can be mounted simply and reliably at a position capable of efficiently radiating UV-light for enhancing the starting performance of a high pressure discharge lamp to discharge chamber without being heated to a high temperature during lighting of the lamp and also adopted to a simple constitution of not increasing the manufacturing cost. A start assisting light source includes an airtight vessel filled with a rare gas and a pipe member that penetrates through the vessel is mounted to an electrode lead which protrudes from the end face of an electrode seal portion secured to a bottom hole of the concave reflector by inserting the electrode lead through the pipe member.
