Scroll compressor including wraps of involute curves on opposite surfaces of an orbiting scroll and a fixed scroll engaged to each other, to form a compression chamber as the orbiting scroll orbits with respect to the fixed scroll, wherein each of the wraps on opposite surfaces of the orbiting scroll and the fixed scroll is formed from two or more involute curves each having a base circle and a point of starting different from each other, thereby permitting to secure a larger compression space for a same sized scroll compressor while reliability of the scroll compressor is not made poor, to reduce centrifugal force and noise occurring the orbiting scroll, and improving stability of the orbiting scroll.
