Compressor

Provided is a compressor comprising a compression mechanism, a motor and a casing, in which the vibration and noise of the compressor due to the vibration of the motor can be reduced. The compressor (1) comprises the compression mechanism (2), the motor (4) connected to the compression mechanism (2) through a drive shaft part (5), and the casing (10) storing the compression mechanism (2) and the motor (4). The motor (4) includes a stator (41), and a rotor (42) disposed on the inside of the stator (41) and connected to the drive shaft part (5). The stator (41) is spot-joined to the casing (10) through stator side welded parts (6a, ..., 6b, ...) provided at different positions in the axial direction of the drive shaft part (5). The stator side welded parts (6a, ..., 6b, ...) are provided at different positions in the circumferential direction of the drive shaft part (5).
