  We study the pion electromagnetic form factor and the dilepton production
rate in hot matter based on the vector manifestation (VM) of chiral symmetry in
which the massless vector meson becomes the chiral partner of the pion, giving
a theoretical framework of the dropping $\rho$ \^^ a la Brown-Rho scaling. The
VM predicts a strong violation of the vector dominance (VD) near the phase
transition point associated with the dropping $\rho$. We present the effect of
the VD violation to the dilepton production rate and make a comparison to the
one predicted by assuming the VD together with the dropping $\rho$.
