The invention discloses a generating device of a surface electromagnetic wave radiation source, which can be applied to the technical field of electromagnetic waves. The plasma excitation unit is used for generating plasma, and the plasma acceleration unit comprises an electron acceleration power supply, a cathode end face, a slow wave circuit, a plurality of insulation spacers, a plurality of acceleration poles and an output end face. An electron beam channel is formed in the middle area of the upper surface of the slow wave circuit and the middle area of the lower surface of the cathode end face, the insulation spacers, the acceleration poles and the output end face, and meanwhile the insulation spacers and the acceleration poles are arranged between the cathode end face and the output end face at intervals. The speed of the plasma in the electron beam channel output by the plasma excitation unit is adjusted through the plasma acceleration unit, so that the electromagnetic wave radiation source under the target frequency, the target bandwidth or the target power can be output, and the electromagnetic wave radiation source with high frequency, wider bandwidth and high power can be obtained.
