The present invention discloses a reciprocating compressor and a manufacturing method thereof. The reciprocating compressor includes a frame installed in a casing, an outer stator having a winding coil and being fixed to the frame, an inner stator disposed in the outer stator with a predetermined gap, and sintered by a powder metallurgy process using metal powder, a rotor having a permanent magnet between the outer stator and the inner stator, a cylinder disposed inside the inner stator of the reciprocating motor for forming a compression chamber, and sintered by a powder metallurgy process using metal powder, a piston slidably inserted into the inner circumference of the cylinder, for sucking and compressing gas by linear reciprocation, and a plurality of resonance springs for elastically supporting the connection part of the piston and the rotor, and inducing resonance of the piston. Accordingly, the cylinder is not deformed by the inner stator, and thus abrasion of the piston and the cylinder by deformation of the cylinder is prevented in advance. Moreover, the reciprocating compressor is easily manufactured by considerably simplifying the manufacturing process.
