-NMR spectra, Knight shift and nuclear spin-lattice relaxation time T1 for CeRu4P12 have been measured in the temperature range between 4.2 and 330 K. Knight shift is almost temperature independent and nearly equal to zero, suggesting that Ce ion seems to be nonmagnetic. Above 150 K, T1 shows activated-type behavior with the gap energy of 0.078 eV. Since T1 is longer than that for LaRu4P12 without 4f-electrons, 4f-spin fluctuation effect on T1 is not dominant for CeRu4P12.
