  It is shown that the anomaly inflow mechanism can be implemented using Wilson
line in odd dimensional gauge theories. An action of Wess-Zumino-Witten (WZW)
type can be constructed using Wilson line. The action is understood in the odd
dimensional bulk space-time rather than in the even dimensional boundary. This
action is not gauge invariant. It gives anomalous gauge variations of the
consistent form on boundary space-times. So it can be used to cancel the
quantum anomalies localized on boundary space-times. This offers a new way to
cancel the gauge anomaly and construct anomaly-free gauge theory in odd
dimensional space-time.
