We proposed a normalized representation of the thermal conductivity function for heat transport in He II in the previous work. In order to check its validity, steady state heat transport characteristics of He II was investigated near T{lambda}. The temperature profiles along the channels were measured at various pressures of 0.1, 1.0 and 1.5 MPa. The measured temperature profiles were analyzed to get the thermal conductivity function near T{lambda}. The validity of the universal heat transport formula was confirmed up to T / T{lambda} = 0.99.
