Abstract: The explanation of the observed baryon asymmetry, i.e., the almost complete absence of antimatter in the visible part of the universe, is one of the most important problems in cosmology. The real asymmetry value can be determined by direct measurements of the fluxes of antinuclei with charges $|Z| \geq 2$ in primary cosmic rays near the Earth. The results of the search for antihelium using data from the PAMELA experiment obtained from June 2006 to December 2009 are presented. No events with a charge of $-2$ have been detected in the rigidity range of $0.6$$600$ GV. An upper limit on the antihelium/helium flux ratio overline $\overline{\mathrm{He}}/\mathrm{He}$ can only appear in a matrix or array has been presented as a function of the energy. An integral upper level of $4.7\cdot10^{-7}$ is the lowest limit at rigidities above $14$ GV.
