The thermal conductivity and thermopower are discussed for the heavy fermion CeCu_4Al compound. CeCu_4Al is paramagnetic and follows the modified Curie-Weiss law with μ_{eff} = 2.53 μ_{B}/f.u. and θ_{P} = - 10 K indicating on the presence of well localized magnetic moments of Ce^{3+} ions. The determined electronic specific heat coefficient γ = 2.2 J mol^{-1}K^{-2} confirms the heavy fermion character of this compound. Thermopower is positive over the whole temperature range and below T_{max} = 25 K falls rapidly. Based on a simple band model the position and width of the 4f peak nearest to the Fermi level have been estimated. The measured total thermal conductivity of the CeCu_4Al compound increases almost linearly with increasing temperature.
