A crank shaft and a scroll compressor including the same are provided to improve the productivity and reliability of crank shaft by analyzing each part of crank shaft accurately and establishing the standards. A crank shaft comprises a first bearing part(11) and a second bearing part(12) formed at an interval, a rotor fixing unit(13) combined in a rotor of a drive motor, and an eccentric part(14) extended from the first bearing part. The eccentric part has a specific eccentricity to the center of axis of the first bearing part or the rotor fixing unit in order to transmit the torque of the drive motor to a compression device. The first bearing part has an outer diameter greater than the sum of the outer diameter of the eccentric part and two times the eccentricity of the eccentric part. |
