We report the first measurement of CP-violation parameters in B(0)->rho(0)gamma decays based on a data sample of 657x10(6)B (B) over bar pairs collected with the Belle detector at the KEKB asymmetric-energy e(+)e(-) collider. We obtain the time-dependent and direct CP-violating parameters, S(rho)(0)gamma=-0.83 +/- 0.65(stat)+/- 0.18(syst) and A(rho)(0)gamma=-0.44 +/- 0.49(stat)+/- 0.14(syst), respectively.
