Claims

[Scope of utility model registration request]

A flash lamp that is made by sealing a rare gas such as xenon or krypton in a bulb as the main component of the luminescent gas, and which transmits visible light and directs long-wave infrared rays of about 800 nm or more toward the plasma inside the bulb. A flash lamp characterized in that a laminated reflective film is provided on the outer surface of the bulb, and at least the outermost layer of the laminated reflective film is a conductive layer, or an electrically conductive transparent film is further provided on the outer surface of the laminated reflective film. .
