The fluxes and flux ratios of charged particles in cosmic rays are presented in the absolute rigidity range from 1 up to 4000 GV. Of particular interest is the energy dependance of the positron flux, which clearly shows the existence of the new source of high energy cosmic ray positrons. In the absolute rigidity range ∼60 to ∼500 GV, the antiproton, proton, and positron fluxes are found to have nearly identical rigidity dependence and the electron flux exhibits different rigidity dependence. The identical rigidity dependence of primary and secondary cosmic ray nuclei fluxes will also be presented.
