A linear compressor is provided, which has a reduced number of front main springs among springs continuously transmitting a force so that a piston can move in a resonance condition. The linear compressor includes a hermetic container to be filled with a refrigerant; a linear motor including an inner stator, an outer stator, and a permanent magnet; a piston linearly reciprocated by the linear motor; a cylinder that provides a space to compress the refrigerant; a supporter piston having a connecting portion connected to one end of the piston, a support portion that extends from the connecting portion, and an additional mass member fixing portion that extends from the connecting portion; front main springs, one end of each of which is supported by one surface of the supporter piston; and one rear main spring, one end of which is supported by the other surface of the supporter piston.
