A compressor includes sliding members arranged to slide relative to each other when compressing a refrigerant. At least one of the sliding members has a resin layer that is formed on the whole area or a portion of at least one sliding surface. The resin layer has an arithmetic mean surface roughness (Ra) of 0.3 or more, or the whole area or a portion of an area opposed to the resin layer is entirely or partially harder than the resin layer and has an arithmetic mean surface roughness (Ra) of 0.3 or more.
