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.
