The sixty five radial velocity measurements of
Cep C (blue visual companion of
Cep A) have been obtained. The evidences are give that
Cep C is spectral binary. The most probable periods of system are: 0d,89986 and 0d,46458. In both cases the
-velocity of
Cep C is in good agreement with mean velocity of
Cep A. It is a strong argument on their physical connection.
The secondary component of
Cep C may have very low mass (near 0.1 solar mass or less).
