Abstract: A sterilization apparatus includes a support member and multiple germicidal light sources. The multiple germicidal light sources are mounted on the support member and emit germicidal light which is light having a wavelength capable of inactivating microorganisms. In addition, respective light exit surfaces of the multiple germicidal light sources face in different directions from one another. Further, an irradiance of the germicidal light delivered to a sterilization target is greater than a minimum irradiance required for sterilization.
