Hard X-ray INTEGRAL observations of SS 433 carried out during 2003-2005 years are presented .
Analysis of precessional and orbital variability is presented .
The width of X-ray eclipse in the 25 - 50 keV range at the precessional phase \psi = 0.1 ( accretion disk is open to observer ) is higher than that in the Ginga 18.4 - 27.6 keV range .
This fact suggests existance the presence of hot extended corona around the supercritical accretion disk .
Spectrum of hard X-rays in the range 10 - 200 keV does not change with the precessional phase which also suggests that hard X-ray flux is generated in the hot extended corona around the accretion disk .
The parameters of this hot corona are : kT = 23 - 25 keV , \tau = 1.8 - 2.8 .
Mass ratio estimated from the analysis of the ingress part of the eclipse light curve is in the range q = m _ { x } / m _ { v } = 0.3 - 0.5 .
