Thermal conductivity of the improper ferroic Tb₂(MoO₄)₃ was measured in the range 0.3 K - 100 K by the method of the stationary heat flow. An additional maximum in thermal conductivity observed at 0.45 K is due to the anomaly of specific heat corresponding to the antiferromagnetic phase transition.
