We have succeeded in growing large-size single-crystals of the four-leg spin-ladder system La2Cu2O5 by the traveling-solvent floating-zone method, and also investigated the thermal conductivity. The thermal conductivity along the leg of the ladder, κb, has been found to be much larger than that perpendicular to the ladder plane, κa. The temperature dependence of κb exhibits a peak at 22 K and a shoulder at 12 K. The peak is a little enhanced by the application of a magnetic field of 1 4T. The large value of κb is explained as being due to the large contribution of magnons to the thermal conductivity.
