On the basis of the Fermi liquid theory, the Kadowaki-Woods ratio $A-\gamma^2$ is evaluated by using a first principle band calculation for typical itinerant $d$ and $f$ electron systems. It is found as observed that the ratio for the $d$ electron systems is significantly smaller than the normal $f$ systems, even without considering their relatively weak correlation. The difference in the ratio value comes from different characters of the Fermi surfaces. By comparing Pd and USn$ 3$ as typical cases, we discuss the importance of the Fermi surface dependence of the quasiparticle transport relaxation.
