We have measured the temperature dependences of the thermal conductivity in the ab-plane, κab(T), and along the c-axis, κc(T), respectively, for the Er-Ba-Cu-O bulk superconductors, which were fabricated by a method of the melt texture growth. Above the critical temperature Tc, the κab decreases quite moderately as increasing temperature or is almost independent of the temperature. Below the Tc, the well-known enhancement is observed but is relatively small. The κc(T) shows the small absolute values and we found that the anisotropy of the thermal conductivity (κabc) for Er-Ba-Cu-O bulks is of about 2-6.
