To provide a UV irradiation device and a UV irradiation method with which it is possible to easily and adequately break down a biofilm.SOLUTION: A UV irradiation device comprises a light source unit having a light source for emitting UV light having a wavelength of 190-240 nm inclusive, and a support body for supporting the light source unit such that a biofilm is irradiated with the UV light emitted by the light source. The UV irradiation device irradiates the biofilm with UV light to break down the biofilm.SELECTED DRAWING: Figure 2 【課題】バイオフィルムを容易かつ適切に分解することができる紫外線照射装置および紫外線照射方法を提供する。【解決手段】紫外線照射装置は、波長１９０ｎｍ以上２４０ｎｍ以下の紫外線を放射する光源を有する光源部と、光源から放射される前記紫外線をバイオフィルムに照射させるべく光源部を支持する支持体と、を備える。この紫外線照射装置は、紫外線をバイオフィルムに照射することで当該バイオフィルムを分解する。【選択図】 図２
