Abstract: The present disclosure relates to a scroll compressor. According to the present disclosure, in a shaft penetration scroll compressor in which an eccentric portion of the rotation shaft is overlapped with a orbiting wrap of the orbiting scroll in a radial direction, when a bearing area between the orbiting scroll and the rotation shaft is A and an end plate area of the orbiting scroll is B, A/B may be formed in a range of 0.035-0.085, and thus it may be possible to obtain a sufficient volume ratio and Sommerfeld number as well as reducing the overall size of the compressor, thereby reducing a frictional loss and abrasion in the compressor.
