Abstract 摘要	We discuss the cosmological implications of electroweak monopole of the standard model. Although the electroweak phase transition is of the first order, the cosmological monopole production comes from the thermal fluctuations of the Higgs field after the phase transition, not the vacuum bubble collisions during the phase transition. But most of the monopoles produced initially are annihilated quickly. As the result the remnant monopole density at present universe becomes very small, of $10^{-11}$ of the critical density. Nevertheless the monopole could become the seed of the primodial blackholes and the large scale structure of the universe, and trigger the electroweak baryon genesis. Moreover it could be the source of the intergalactic magnetic field. We discuss how to detect the remnant monopole experimentally.
