A light emission surface is provided on a distal end on a second electrode introducing part side of a light-emitting tube of a flash lamp including a first electrode introducing part and the second electrode introducing part, and a plurality of flash lamps are arranged in a standing manner on a top plate of a processing chamber so that the light emission surface faces the inside of the processing chamber.

A laser driven lamp includes a metallic main body having a columnar shape. The lamp also includes an ellipsoidal reflecting surface formed in the main body such that the ellipsoidal reflecting surface has a focal point at which the laser beam converges. The lamp also includes a light exit window in front of the ellipsoidal reflecting surface. The light exit window transmits ultraviolet light. The lamp also includes a laser beam passing hole formed at a predetermined position of the main body such that this hole penetrates the main body in an optical axial direction of the lamp. The lamp also includes a light entrance window behind the laser light passing hole such that the laser beam is incident to the light entrance window. The main body, the light exit window and the light entrance window form a closed space to contain a light emitting gas.
