We study Q-ball formation in the expanding universe on 3D lattice simulations. We obtain detailed Q-ball charge distributions, and find that the distribution is peaked at Q^<3D>_<peak>≃1.9×10^<-2>(|Φ_<in>|/m)^2, which is greater than the existing result by about 60%. Based on the numerical simulations, we discuss how the Q-ball formation proceeds. Also we make a comment on possible deviation of the charge distributions from what was conjectured in the past.
