  We report on the results of measuring the chromoelectric fields in a flux
tube created by a static quark-antiquark pair in the finite-temperature SU(3)
gauge theory. Below the deconfinement temperature the field behavior is similar
to the zero-temperature case. Above the deconfinement temperature the field
shape remains the same, but the field values drop when the distance between
quark and antiquark increases, thus showing the disappearance of confining
potential.
