PROBLEM TO BE SOLVED: To provide a testing device for interference rejection capability which can use a low-cost and low-output power amplifier. SOLUTION: The testing device for interference rejection capability 1 comprises a signal generator 10 generating a high-frequency signal, a radiation antenna 5, an amplifier 13, and a table 3 mounting a device to be tested 2. The radiating antenna 5 is equipped with an electromagnetic horn 4 and a waveguide 8, having the same aperture as the aperture of the electromagnetic horn 4. The electromagnetic horn 4 and the waveguide 8 are made to be installed on the same axial line as the radiation axis line 12 of the electromagnetic horn 4 and close to each other. The electromagnetic waves, radiated from the electromagnetic horn 4, are guided to the waveguide 8, and the guided electromagnetic waves are radiated to the device to be tested 2.
