Properties of the axion in PQWW model is considered. In this model, axion appears as a new phase of the Higgs field. From a general Higgs potential which is renormalizable and invariant under UPQ(1) transformation, we consider the interaction of the axion with leptons and quarks. Based on these results, axion production in e⁺e^- collision is calculated in detail. The numerical evaluation shows that the axion can be detected in
experimental conditions.
