Fluctuation of a single step on the vicinal surface in thermal equilibrium is investigated by Monte-Carlo simulation for the ASOS (absolute solid-on-solid) model. The relation W2(y) = G(y)/ρ2 (at large y) between the squared step width W2(y) and the height-height correlation function G(y), which had been predicted by the capillary wave theory for a vicinal surface with the step density of ρ [T. Yamamoto et al.: J. Phys. Soc. Jpn. 63 (1994) 915], is confirmed by the simulation.
