Abstract
Provided is an ultraviolet light irradiation device that is capable of causing effective inactivation of microorganisms as well as a method of using the ultraviolet light irradiation device.An ultraviolet light irradiation device includes a light source that radiates ultraviolet light with a wavelength in a range of 190 nm to 235 nm; a housing that houses the light source; an extracting portion that extracts the ultraviolet light that is radiated from the light source and causes it to be directed toward an exterior of the housing; and a diffusing member that diffuses the ultraviolet light.
