A scroll compressor formed with a pair of compression chambers, wherein a refrigerant being discharged from the pair of compression chambers is discharged through one discharge port, wherein volume reduction gradients of the pair of compression chambers are different from each other, wherein bypass holes bypassing a portion of the refrigerant prior to discharging the refrigerant compressed in each of the pair of compression chambers through the discharge port are formed at each of the pair of compression chambers, wherein an entire cross-sectional areas of the bypass holes formed at the pair of compression chambers, respectively, are different from each other, and wherein the entire cross-sectional area of the bypass holes formed at a compression chamber of the pair of the compression chambers with a larger volume reduction gradient between the pair of compression chambers is formed to be larger than an entire cross-sectional area of the bypass holes formed at the other compression chamber of the pair of compression chambers.
