By using STS, combined with STM imaging, the STS spectra d(lnI)/d(lnV) -eV were measured point by point along a line on the surface of a single crystal graphite. The local density of states (LDOS) around the Fermi level EF obtained from the spectra showed basically an agreement with that of theoretical calculation. By plotting the energy positions of the LDOS peaks around EF with respect to the measurement positions, the spatial variations of the energy band of graphite close to EF were shown. With a discussion of the local electronic structure around the ine-quivalent A, B type atoms on the surface, a simple model calculation for the spatial variations of the energy band was conducted and that showed an agreement with the experimental results. By comparison of the results, the site of A type atoms on the graphite surface, which did not appear in the STM image, was determined.
