It is an object of the present invention to provide a linear compressor in which a driving spring and a elastic supporting member for supporting a compressing mechanism portion are disposed such that a piston and the compressing mechanism portion move in reversed phases so that vibration of a hermetic vessel is canceled out. The linear compressor comprises a hermetic vessel having a compressing mechanism portion and a linear motor therein. The linear motor comprises a mechanism member which provides the piston with reciprocating driving force and a stator which is fixed to the cylinder and which forms a reciprocation path for the mechanism member, the compressing mechanism portion and the linear motor are classified into a piston-side mechanism member and a cylinder-side mechanism member, the piston-side mechanism member includes the piston, the mechanism member and another mechanism member which is movable together with the piston and the mechanism member, the cylinder-side mechanism member includes the cylinder, the stator and another mechanism member fixed to the cylinder or the stator, the cylinder-side mechanism member is elastically supported in the hermetic vessel by the first elastic member, and a reciprocating force in the axial direction is given to the piston-side mechanism member by a second elastic member whose one end is supported by the hermetic vessel.
