The preheating after the inflation, which can be interpreted as particlecreation in the oscillating inflaton background, provides a state far fromthermal equilibrium. We extend the field theoretical treatment of thepreheating by Linde et al. to the case of multicomponent complex scalars toshow that some charges are created in this process, if C and CP are violated. Anew possibility of baryogenesis based on this mechanism is also discussed.Comment: 18 pages, LaTeX 2e, 3 eps figure
