Abstract. We consider the behaviour of the axion mass as a function of Higgs coupling constants. The analysis is significantly simplified when we identify the axion field with the phase difference of the Higgs neutral components. Spontaneous CP-violation is induced by VEV of the axion field. The estimation of the axion mass for any values of $\delta _{\rm CP}$ and $\tan \beta$ shows inconsistency of MSSM with the present experimental results.
