Disclosed is an asymmetric scroll compressor. The compressor includes an orbiting scroll possessing a wrap which has an involute curve-shaped configuration, an Oldham ring arranged on a lower surface of the orbiting scroll to prevent the orbiting scroll from being reversely rotated, and a fixed scroll having a wrap which has an involute curve-shaped configuration and is engaged with the wrap of the orbiting scroll such that compression chambers are defined between the wraps of the orbiting and fixed scrolls by rotating motion of the orbiting scroll. The wrap of the fixed scroll further extends within the range of 180° than the wrap of the orbiting scroll in a direction where an involute curve extends. A center of a base circle of the orbiting scroll wrap is positioned within a region which ranges circumferentially between 30° in a direction where the existing orbiting scroll wrap is wound up and 60° in a direction where the existing orbiting scroll wrap is extended, when measured from a straight line connecting a center of a base circle of the existing orbiting scroll wrap with an outer end of the existing orbiting scroll wrap, and radially between 0.1 times and 0.5 times a rotating radius of the orbiting scroll wrap.
