In the light of the notable role played by a 45-plet of Higgs particles SU(5) grand united theory a harmless axion containing a component from a Higgs 45-plet is derived following the Dine-Fischler-Srednicki in the SU(5) x U(1)/sub PQ/ model PQ refers to Peccei and Quinn. The breaking of U(1)/sub PQ/ through instanton effects into Z/sub 6/ gives a useful relation between vacuum expectation values of 45 and 5 Higgs fields. An estimation of the cosmological baryon-to-entropy ratio is also presented, and is consistent with the present observations.
