  Optical reflectivity spectra of La(1-x)Sr(x)MnO(3) (0<=x<=0.30) were measured
on cleavage surfaces of single crystals. The optical conductivity $\sigma(w) of
ferromagnetic-metal La(0.70)Sr(0.30)MnO(3) is characterized by a Drude-like -
but not simple Drude - component with large spectral weight below 1.6 eV, which
yields a large effective carrier number N*_eff consistent with the results of
Hall coefficient and specific heat measurements. The present result
demonstrates that the previous result of "small Drude weight" originates from
the damage of the sample surface. The Sr-substitution effect on the electronic
structure and the origin of the unconventional $\sigma(w) are also discussed.
