Abstract (en)
A heater according to an embodiment includes a tubular portion, a coil which is provided inside the tubular portion and extends along a tube axis of the tubular portion, and a coating which is provided on an outer surface of the tubular portion and in which a first film and a second film having a higher refractive index than a refractive index of the first film are alternately superposed. A gas containing krypton as a main component or a gas containing xenon as a main component is sealed inside the tubular portion. When a tube outer diameter of the tubular portion is set to D (mm) and a wall thickness of the tubular portion is set to T (mm), the following expression is satisfied:T/D≥0.09and D≥11.8mm.
