Disclosed is a scroll compressor in which a compression chamber (24) is formed by engaging a pair of fixed scroll and a rotating scroll in each other, the fixed scroll and the rotating scroll respectively comprising an end plate and a spiral wrap (18B, 19B) erected on the end plate, and a discharge port (25) to discharge a fluid compressed in the compression chamber (24) is provided in the center section of the fixed scroll. The discharge port (25) has a shape of a deformed long hole in which both of the ends are circular holes (25A and 25B), which are combined by two surfaces (25C, 25D) having a width (W) smaller than the hole diameter (D) of the circular holes.
