Neutron diffraction experiments were performed to investigate a nature of the antiferromagnetic ordered phase below TN = 5.0 K of the pressure-induced superconductor CeIrSi3. We succeeded in observing incommensurate magnetic peaks characterized by the wave vector τ = (±0.265, 0, 0.43). In contrast to the magnetic structure of CeRhSi 3, the observed magnetic structure is incommensurate both along the a and c directions. The antiferromagnetic ordered state in CeIrSi3 could be interpreted as a spin-density wave formation.
