It is an object of the present invention to provide a high-efficiency linear compressor in which even if a compression chamber is defined utilizing an inner space of the linear motor to reduce its size, an amount of heat transmitted from the linear motor to the compression chamber can be reduced by forming a space between the linear motor and a cylinder which defines the compression chamber. The linear compressor comprises a cylinder having a flange and a cylindrical portion supported in a hermetic vessel by a support mechanism, a piston movably supported in the cylindrical portion along an axial direction thereof, a spring member applying an axial direction to the piston, and a linear motor having a stator fixed to the flange of the cylinder and disposed around an outer periphery of the cylindrical portion and a moving member coupled to the piston, wherein a space is formed between the stator and the cylindrical portion.
