The present invention provides a UV sterilization module capable of suppressing a generation of ozone inside and outside a device, and emitting UV rays having a wavelength of near 200 to 230 nm, in particular UV rays having a wavelength of 222 nm at a high luminous intensity, and a UV sterilization apparatus using the UV sterilization module. According to the UV sterilization apparatus of the present invention, bacteria or viruses existing on a surface of the biological tissue may be selectively UV sterilized without harming animal cells such as human cells, and a generation of ozone harmful to the skin may be reduced. |
