The energy spectra of the main components of the primary cosmic rays were measured directly in a series of ten balloon flights which began in 1975 and continued until 1987. The results found on the basis of all the data accumulated are reported in this letter. The spectrum of primary protons at energies above 10 TeV is shown to be steeper than at lower energies and also steeper than the spectra of other nuclei.
