We report the broadband X-ray spectra of the ULIRG UGC 5101 in the 0.25-100 keV band observed with Swift/BAT, NuSTAR, Suzaku, XMM-Newton, and Chandra. A Compton-thick AGN is detected above 10 keV and the intrinsic 2-10 keV luminosity is determined to be 1.4 × 10^43 erg/s. We find that UGC 5101 shows the ratio between the [O IV] line and 2-10 keV luminosities similar to those of normal Seyfert galaxies, along with other ULIRGs, indicating that AGNs in many local ULIRGs do not look extraordinary (i.e., extremely X-ray faint).
