Under the assumption of Abelian dominance in QCD, we have shown that chiralcondensate is locally present around each QCD monopole. The essence is thateither of charge or chirality of a quark is not conserved, when the low energymassless quark collides with QCD monopole. In reality, the charge is conservedso that the chirality is not conserved. Reviewing the presence of the localchiral condensate, we show by using chiral anomaly that chiral non symmetricquark pair production takes place when a quark is putted in a vacuum withmonopole condensation, while chiral symmetric pair production takes place in avacuum with no monopole condensation. Our results strongly indicate that thechiral symmetry is broken by the monopole condensation.
