In terms of σ-model constructed from a well-defined quantum theory with the aid of fermionic coherent states, we study the effect of chiral breaking term in the fermion action. We find the effect could not be wiped out, when gauge fields coming in, by any counter terms, then remains as the form of an anomaly. We also discuss the consequences of the anomaly in terms of π^0→2γ decay and η' mass being heavier than others ( U(1) problem).
