A compressor and a method of manufacturing the same are disclosed. The compressor includes a piston having a cylindrical shape and having formed therein a suction space, in which refrigerant gas is sucked, and a cylinder having, as a space formed therein, formed therein a compression space, in which refrigerant gas is compressed, by reciprocation of the piston in an axial direction. A gas inflow passage having one side communicating with a gas pocket outside the cylinder and the other side communicating with a space formed in the cylinder is formed in the cylinder, and the piston includes a plurality of fine irregularities formed in an outer circumferential surface of a guide facing the cylinder and provided at a position corresponding to the gas inflow passage.
