Electromagnetic clutch and compressor equipped therewith

The present invention aims to provide an electromagnetic clutch capable of decreasing the impact noise generated when the armature plate and the driving rotor are coupled. The present invention further aims to provide a compressor equipped with this electromagnetic clutch. An electromagnetic clutch in the present invention comprises an armature that has a driving rotor (32), which is connected so as to be linked to a driving source and which includes a coil (33), and an armature plate (34), which is disposed so as to face said driving rotor and which has the same rotational axis thereas, and an end face (32a) of said driving rotor and said armature plate are attached or separated by said coil's magnetic force when a voltage is applied to excite said coil thereby intermittently coupling said driving rotor and said armature, wherein said armature plate (34) comprises a plurality of plate members (41) laminated together, and at least a part of each of said plate member being connected to the other plate members.
