摘要

Provided is an ultraviolet irradiation device capable of increasing the irradiance at an affected site (target cells) even when ultraviolet light having the same intensity is emitted. This ultraviolet irradiation device is provided with: a device body configured to be capable of emitting ultraviolet light from a light emission unit; an ultraviolet-transparent substrate disposed on the light emission unit; and an elastic member which is disposed on the surface of the substrate facing away from the device body and made of an ultraviolet-transparent material.
