The three-dimensional ±J Ising spin glass model is investigated by means of Monte Carlo simulation. In uniform fields of various strength, the Edwards-Anderson susceptibility χ_<EA> is calculated at T=0.9J which is lower than the transition temperature in the zero-field case. It is found that χ_<EA> decreases monotonically when the field strength is increased and that the data do not suggest a phase transition in a finite field. The best parameters for the scaling function of the form χ_<EA>(H)≃l^ψχ^^~_<EA>((H-H_c)l^<-φ>) are estimated to be H_c=0.00(10)J, ψ=2.16(22) and φ=-1.13(6). These results support the hypothesis that the phase transition does not exist in a finite magnetic field.
