Abstract: In the $N=2$ supersymmetric Yang–Mills theory, the instanton contribution to the $R$-symmetry anomaly resulting from noninvariance of the collective coordinate measure is investigated. The one-instanton contribution is in agreement with the exact result. Multi-instanton contributions are investigated qualitatively.
