1. A compressor, comprising:
a casing;
a drive motor provided in an inner space of the casing;
a rotating shaft coupled to the driving motor to rotate;
an orbiting scroll comprising an orbiting end plate coupled to the rotating shaft, and an orbiting wrap extended along a circumference of the orbiting end plate; and
a fixed scroll comprising a fixed end plate provided to face the orbiting scroll and a fixed wrap extending from the fixed end plate to engage the orbiting wrap to compress refrigerant,
wherein the fixed scroll further comprises:
a suction port penetrating through the fixed end plate to receive the refrigerant and spaced apart from an outermost of the fixed wrap,
a discharge port penetrating the fixed end plate to discharge the refrigerant, and spaced apart from an innermost of the fixed wrap, and
a bypass portion comprising a first hole portion including holes of bypass hole groups located inside from the fixed wrap with respect to a second shaft receiving hole of the fixed scroll to discharge the refrigerant, and a second hole portion including holes of bypass hole groups located outside far away from the fixed wrap with respect to the second shaft receiving hole of the fixed scroll to discharge the refrigerant, and wherein a total area of the second hole portion is greater than a total area of the first hole portion.
