  The supersymmetric contribution to the muon g-2 is studied in light of the
finalization of the LEP electroweak precision data. The recent precise
measurement of the muon g-2 of E821 experiment is explained well by the
relatively light chargino and sleptons. We find that such the MSSM parameter
space is also favored from the electroweak precision data, in which the fit to
the data is better than that of the SM (\Delta \chi^2_{min} \sim -2), if the
lighter chargino has a mixed higgsino-wino character (\mu/M_2 \sim 1). The
models with light gauginos (\mu/M_2 > 10) or light higgsinos (\mu/M_2 < 0.1)
also show the better fit over the SM, but the improvement is marginal as
compared to the case of the mixed higgsino-wino case (\mu/M_2 \sim 1).
