We report results of SUZAKU observation of anomalous X-ray pulsar 1E 1048.1-5937 performed in November 2008. We perform a spectral and a timing analysis on XIS (0.2-12 keV) data. It is found that only power law plus blackbody model (kT　approximately 0.604 keV, photon index approximately 3.2) is acceptable with a flux level of 7.4 x 10(exp -12) ergs/(sq cm s) at 2-10 keV energy bands, which is consistent with the previous study. No line features have been detected in the spectrum. The pulse period (p = 6.4595 sec) and the pulsed profile have been derived by epoch folding method, and the pulsed fraction is estimated to be 0.5. The period, pulse profile and pulsed fraction are also consistent with previous observations. We also perform a spectral analysis on PIN data, and a marginal flux has been detected in the range 14-22 keV with only 3.3 confidence level.
