  The gluon condensation (GC)-effects in high energy cosmic rays are
investigated. After a brief review of the GC, several examples including
gamma-, electron-, and positron-spectra in a broad GeV$\sim $TeV region can be
explained by the GC-effects. We find that the GC may break the power-law of the
cosmic ray spectra if the energy of accelerated protons exceeds the
GC-threshold. The GC is a new phenomenon that is not yet known, it provides a
new window to understand the high energy cosmic ray spectra.
