An ultra violet rays generator by means of microwaves excitation which comprises a microwave generator for generating microwaves, a microwave cavity directly connected to said microwave generator, an ultra violet ray (UV) reflector having a window for introducing microwaves on the upper part thereof, detachably secured in said microwave cavity, and an ultra violet rays lamp disposed under said window and near the inside of said UV reflector, said UV reflector being composed of a light-transmitting base, and an inteference film formed on said base. According to the generator, it is detachable of only the UV reflector without changing the capacity of the microwave cavity, and thus becoming changeable of only the directions or configurations of the UV without changing microwave efficiency of the microwave cavity, and furthermore, it can obtain the UV of low temperature, exclusive of infra red rays originally included in the UV. Moreover, the mechanism thereof is simplified by omitting the wave guide, and thus, it becomes easy for the production thereof.
