The IUE images of the atmospheric eclipsing binary VV Cep (M 2 Ia e + B, P = 20.3 yr) were studied. The absorption and emission lines in the high-resolution spectra were identified. No interstellar absorption lines were detected despite the large degree of reddening. The comparison of the UV energy distribution of VV Cep after the end of the eclipse with several standard stars observed with IUE gives a spectral type A0 II for the companion.
