摘要: Provided is a compact ultraviolet irradiation apparatus which is capable of emitting ultraviolet radiation with high efficiency. This ultraviolet irradiation apparatus includes, in a vessel, a semiconductor multi-layered film element and an electron beam irradiation source for irradiating the semiconductor multi-layered film element with an electron beam, the vessel being hermetically sealed to have a negative internal pressure and having an ultraviolet transmitting window. Furthermore, the semiconductor multi-layered film element includes an active layer having a single quantum well structure or a multi quantum well structure of In x Al y Ga 1-x-y N (0 ‰¤ x
