We calculate thermal photon and electron pair
distribution from hot QCD matter produced in high
energy heavy-ion collisions, based on a hydrodynamical
model which is so tuned as to reproduce the
recent experimental data at CERN SPS, and compare these
electromagnetic spectra with experimental data given by CERN WA80
and CERES. We investigate mainly the effects of the off-shell
properties of the source particles on the electromagnetic spectra.
