We study on the electroweak baryogenesis problem in the vectorlike quark model. This model can add to the minimal standard model the extra CP-violation source which breaks CP spontaneously. Using charge transport mechanism suggested by Nelson et al, we can get the net hypercharge flux : f_Y〜10^<-5>. This result could nicely explain the present baryon to entropy ratio : p_B/s〜10^<-9>.
