摘要： The present invention provides a metal halide lamp in which the change of the color temperature is suppressed regardless of the orientation of the light emitting bulb in use. The metal halide lamp includes a light emitting bulb of translucent ceramics that includes a light emitting portion and tubular portions that are connected to the light emitting portion. The light emitting portion includes a liquid holding portion on the inner surface of the light emitting portion so as to hold a liquefied substance that moves on the inner surface toward one of the tubular portions. The internal diameter d of the light emitting bulb at the liquid holding portion satisfies 0.4 D
