High field ESR measurements have been performed on (DI-DCNQI)2Ag single crystals at 1.9 K under 1 bar and 2.4 kbar in the frequency region from 70 to 160 GHz using the pulsed magnetic field up to 8 T. This compound undergoes the antiferromagnetic transition at TN = 5.5 K and the antiferromagnetic resonance (AFMR) was observed under 1 bar. The AFMR was also observed under 2.4 kbar and the zero-field antiferromagnetic gap is found to be reduced under pressure. The origin of this result is discussed.
