PROBLEM TO BE SOLVED: To provide a radio communication suppression device that sufficiently suppresses radio communication in a specific area, and that is downsized. SOLUTION: The radio communication suppression device 101 for suppressing radio communication of radio communication apparatuses in a predetermined area is equipped with: a noise generator GEN for generating a noise signal; a first distributor 2 for distributing the noise signal generated by the noise generator GEN; a plurality of band pass filters 3A, 3B, 3C, 3D that receive the noise signals distributed by the first distributor 2, respectively, and attenuate a component out of a predetermined frequency band of the distributed noise signals, the predetermined frequency band being different among the band pass filters; a synthesizer 5 that synthesizes the plurality of noise signals that have passed through the plurality of band pass filters 3A, 3B, 3C, 3D; and an antenna part ANT that outputs the noise signal synthesized by the synthesizer 5 to the predetermined area.
