Visible-light excited micro-Raman spectroscopic measurements were performed for sliding materials consisting of graphite, in order to characterize structural changes of the material surface induced by electric sliding test with sparkling. Raman spectra of the sliding materials after the test showed a Raman band around 1360 cm^-1 besides the usual spectra of graphite. The Raman band, which indicates degradation and disordering in the graphite structure, grew with increasing sparking voltage, while scarce growth of the band appeared under non-electric sliding. Correlation of the structural change at the surface with wear endurance of the sliding materials was also recognized in an accelerated sliding test. It is expected that the Raman measurement will be a convenient method for evaluating the endurance of the sliding materials.
