We have performed high pressure X-ray diffraction measurements on a powder sample of the tetragonal heavy-electron compound URu2Si2 at low temperatures and pressure up to 3 GPa, in order to investigate a pressure-induced phase transition at Pc = ∼ 1.5 GPa, which was indicated in the neutron diffraction experiment under pressure. The pressure variations of the lattice parameters a and c at 15 K decrease monotonously with increasing pressure. No discontinuity of the lattice parameters of URu2Si2 around Pc is observed within experimental error.
