Abstract
A sliding material based on graphite-added resin containing 5 to 60% by weight of graphite particles having an average particle diameter of from 5 to 50 μm, and a degree of graphitization of 0.6 or more, with the balance being one or more of polyimide resin and polyamide-imide resin, and further, the number of the graphite particles having a minimum diameter/maximum diameter ratio (hereinafter referred to as “particle ratio”) of 0.5 or more amounts to 50% or more of the total number of the graphite particles observed in a photograph of an optional cross section of the sliding material based on graphite-added resin.
