Abstract: This paper is the second in a series devoted to the hard X-ray 17-60 keVwhole sky survey performed by the INTEGRAL observatory over seven years. Herewe present a catalog of detected sources which includes 521 objects, 449 ofwhich exceed a 5 sigma detection threshold on the time-averaged map of the sky,and 53 were detected in various subsamples of exposures. Among the identifiedsources with known and suspected nature, 262 are Galactic 101 low-mass X-raybinaries, 95 high-mass X-ray binaries, 36 cataclysmic variables, and 30 ofother types and 219 are extragalactic, including 214 active galactic nucleiAGNs, 4 galaxy clusters, and galaxy ESO 389-G 002. The extragalactic |b|>5deg and Galactic |b|<5 deg persistently detected source samples are of highidentification completeness respectively ~96% and ~94% and valuable forpopulation studies.
