In a substrate processing method of polishing a periphery of a substrate, in a state where a first polishing surface to which abrasive grains that include particles having a chemical effect on an oxide-silicon-series or nitride-silicon-series film as a main component have been fixed is brought into contact with the periphery of a semiconductor substrate, polishing the periphery of the substrate by sliding the substrate and the first polishing surface. Moreover, in a state where a second polishing surface to which abrasive grains mainly having a mechanical effect have been fixed is brought into contact with the periphery of the substrate, polishing the periphery of the substrate by sliding the substrate and the second polishing surface.
