Angular distribution of the angular momentum flux proceeding from a rotating electric dipole is shown to have a maximum in the plane of rotation of the dipole. The conclusion is made about an orbital character of this angular momentum. It is affirmed that, besides this flux, there is a flux directed perpendicularly to the plane the rotation, directed just as a radiation of circular polarization is directed. For a calculation of the flux an expressions which are absent in modern electrodynamics are used. So, it is emphasized that modern electrodynamics is not full.
