We discuss verifiability of electroweak baryogenesis in an extended Standard Model, where an extra Higgs doublet, a real singlet and electroweak-interacting fermions are added. In the model, while the real singlet plays a role in having first order electroweak phase transition, a new CP-violating source is supplied by interactions between bubble walls and new fermions. It is shown that the parameter region for the successful BAU can be verified by Higgs physics and electric dipole moments of electron and nucleons in near future.
