In this work, inelastic neutron scattering spectra of powder CeOs4Sb12 sample were collected at different temperatures using LAM-D neutron spectrometer at KEK pulsed neutron source. The result indicates that the CeOs4Sb12 skutterudite is a Kondo insulator with a c-f interaction of 3.1 meV. The Debye temperature is determined as 317 K. %K inelastic neutron scattering %K filled skutterudite %K Kondo insulator
