  We propose a new electroweak baryogenesis scenario in high-scale
supersymmetric (SUSY) models. We consider a singlet extension of the minimal
SUSY standard model introducing additional vector-like multiplets. We show that
the strongly first-order phase transition can occur at a high temperature
comparable to the soft SUSY breaking scale. In addition, the proper amount of
the baryon asymmetry of the universe can be generated via the lepton number
violating process in the vector-like multiplet sector. The typical scale of our
scenario, the soft SUSY breaking scale, can be any value. Thus our new
electroweak baryogenesis scenario can be realized at arbitrary scales and we
call this scenario as a scale free electroweak baryogenesis. This soft SUSY
breaking scale is determined by other requirements. If the soft SUSY breaking
scale is O(10) TeV, our scenario is compatible with the observed mass of the
Higgs boson and the constraints by the electric dipole moments measurements and
the flavor experiments. Furthermore, the singlino can be a good candidate of
the dark matter.
