In this paper, the conformal invariance and Mei symmetry for a generalized Hamilton system under infinitesimal transformations are discussed in details. A necessary and sufficient condition for conformal invariance of systems to be Mei symmetry is given. We get the Mei conserved quantities of the conformal invariance. Finally, an example is given to illustrate the application of the result.
