PROBLEM TO BE SOLVED: To provide a scroll compressor capable of achieving both of securing force and seal performance without inducing a cost increase due to addition of parts or an efficiency degrading due to a residual stress. SOLUTION: In a fixing surface 25 at which a fixed scroll 6 and a body frame 5 are fixed in close contact together, a surface roughness of a fixing surface 25b of the body frame or a fixing surface 25a of the fixed scroll is set greater than the surface roughness of the other fixing surface. Thus, numerous micro protrusions 27a are formed on the fixing surface of the greater roughness side. The micro protrusions 27a are fitted into the other securing surface with a bolt-tightening force to suppress a slip of the fixing due to a radial load, and the seal performance of the securing surface 25 can be secured as well.
