PURPOSE: A linear compressor mounted with two pistons is provided to increase the compression efficiency by performing a compression stroke of two times with one time stroke of two integrally formed pistons. CONSTITUTION: A linear compressor mounted with two pistons includes a main body, a cylindrical outer stator(310) mounted in the main body and winded with coil(312) at a predetermined position, a cylindrical inner stator(315) mounted apart from an inner peripheral surface of the outer stator with a predetermined distance for forming an air gap with the outer stator, a cylinder integrally coupled with an inner peripheral surface of the inner stator and formed with first and second cylindrical parts toward a central part from top and bottom surfaces, and a piston assembly(360) having a first piston(320) at an upper part for sliding in the first cylindrical part, a second piston(340) at a lower part for sliding in the second cylindrical part, and a connection element(325) connecting the first and second pistons and integrally formed with a permanent magnet(330) at a predetermined position for vertically reciprocating due to an electromagnetic interaction with the coil of the outer stator.
