Abstract
A purification apparatus includes an ultraviolet lamp (41) emitting an ultraviolet ray with a wavelength having ozone generating effect and an ultraviolet ray with a wavelength having sterilizing effect and an accommodator (43) accommodating the ultraviolet lamp (41) in an accommodation space thereinside. The accommodator (43) includes a transmission portion transmitting the ultraviolet ray with a wavelength having sterilizing effect. A gas supplied from an oxygen introducing portion (50) into the accommodation space contains oxygen. Thus, ozone is generated in the accommodation space due to the ozone generating effect of the ultraviolet ray emitted by the ultraviolet lamp (41). The ozone generated in the accommodation space is exhausted from an ozone exhausting portion (51).
