A hermetic compressor and a refrigeration cycle device having the same are provided. An oil separator is installed either outside or inside of a casing to separate oil from a discharged refrigerant and an oil pump driven by a driving force of a motor is used to recollect the oil separated in the oil separator, whereby the separation between oil and refrigerant can effectively be performed and also a fabricating cost can be reduced. Also, an introduction of the separated refrigerant back into the compressor can be prevented so as to improve a cooling capability of the refrigeration cycle device. In addition, the oil pump is driven by the driving force of the motor, resulting in a simple configuration of the compressor and a reduction of a fabricating cost of the compressor.
