The angle of inclination of the orbit (i = 65 + or - 1 deg) is determined from an analysis of the light curves of the CQ Cep system in U, V, and R filters. The parameter L3, characterizing the relative luminosity of the 'uneclipsed' common envelope in the CQ Cep system is determined: L3(U) is approximately 0; L3(V) = 0.10; L3(R) = 0.29. The radius of the core of the WN 7 star is found to be 11 + or - 1 solar radii. The brightness and color temperatures (Tb and Tc) were determined to be Tb not less than approximately 50,000 K and Tc roughly equal to 50,000 K. The mass of the WN 7 star was found to be approximately 31 solar masses. On the H-R diagram the core of the WN 7 star was found to occupy a position intermediate betweeen the main sequence and the sequence of homogeneous helium stars.
