  The Hawking radiation in the vacuum of the spontaneous symmetry breaking in
the gauge-Higgs-Yukawa theory is investigated by a general relativistic
formulation of the the ballistic model. The restoration of the symmetry on the
horizon and the formation of the spherical domain wall around the black hole
are shown even if the Hawking temperature is lower than the critical
temperature of the phase transition in the gauge-Higgs-Yukawa theory. When the
Hawking temperature is much lower than the critical temperature, the domain
wall closely near the horizon is formed. The wall is formed by the field
dynamics rather than the thermal phase transition.
