Abstract: A compressor is provided which is configured to allow lubrication of a thrust surface through an oil groove formed in a thrust surface of a fixed scroll. Also, a scroll compressor is provided which smoothly supplies oil to a thrust surface of a fixed scroll by including a fixed scroll having an oil groove formed in the thrust surface of a fixed scroll sidewall, and allows an injection pressure acting on an orbiting scroll in an upward direction to be added by supplying the oil guided to the oil groove to the thrust surface of the fixed scroll such that an overturn moment generated in the orbiting scroll may be offset.
