It is an object of the present invention to provide an efficient and reliable linear compressor in which an axial length center of the moving member connected to a piston is previously deviated toward a compression chamber with respect to an axial length center of the stator, the axial length center of the moving member and the axial length center of the stator are substantially aligned with each other at the time of operation. The linear compressor comprises a cylinder supported in a hermetic vessel by a support mechanism, a piston which is supported concentrically with the cylinder such that the piston can move in an axial direction of the cylinder, and which forms a compression chamber between the cylinder and the piston, a spring mechanism for applying an axial force to the piston, and a linear motor portion having a moving member connected to the piston through a holding member and a stator fixed to the cylinder to form a magnetic path between the stator and the moving member, the linear motor portion generating thrust for moving the piston in its axial direction, wherein the linear compressor further comprises aligning means for aligning an axial length center of said stator and an axial length center of said moving member with each other at the time of operation.
