The present invention re a main housing unit with an intake port which receives a refrigerant intake from outside; a driving unit which generates the torque by being inside the main housing unit; a scroll compressing unit with a fixed scroll of which the position is fixed by being joined to the main housing unit and which includes a rotary wrap of a spiral shape which is rotated by the torqued transmitted via the driving unit and a fixed wrap of a spiral shape which is engaged with a rotary wrap; and a discharge housing unit which is joined to the main housing unit and which includes an inlet receiving the inflow of a high-pressured refrigerant compressed by the scroll compressing unit and a discharge port through which the refrigerant flow via the inlet. The discharge housing unit is formed into a spiral shape from the inlet in the circumference direction corresponding to a discharge passage connected to the discharge port formed on the outer circumference and a direction of the discharge passage and includes the connection passage connected to the discharge passage and a resonant chamber with a resonance room having the volume which is larger than the connection passage to reduce noise or pulses of a refrigerant discharged from the scroll compressing unit and connected to the discharge passage via the connection passage.
