A reciprocating compressor includes: a cylinder installed inside a casing and having a space therein; a piston disposed inside the cylinder; an inner stator fixed at an outer circumference of the cylinder; a magnet fixed at an outer circumference of the inner stator; and an outer stator disposed to maintain a certain distance from an outer circumference of the magnet. Accordingly, the number of components is reduced thus to reduce a manufacturing cost, and performance can be also improved.
