Abstract: A linear compressor and a method of manufacturing a linear compressor are provided. The linear compressor may include a shell including a suction inlet, a cylinder having a compression space, in which a refrigerant suctioned in through the suction inlet may be compressed, a piston reciprocated within the cylinder, a first surface treatment disposed on an outer surface of the piston, the first surface treatment having a first hardness value, which is a measured hardness value, and a buffer disposed between the outer surface of the piston and the first surface treatment. The buffer may have a second hardness value, which is a measured hardness value. The first hardness value of the first surface treatment may be greater than the second hardness value of the buffer.
