A linear compressor includes a piston that reciprocates on a spring central axis extending in an axial direction and a spring that axially elastically supports the piston. The spring includes a plurality of spring strands. The spring strands each include a spring body spirally extending along a spring central axis C, a front spring link forming an end of the spring body by extending from a side of the spring body, and a rear spring link forming the other end of the spring body by extending from the other side of the spring body. Of the spring strands, the front spring links are disposed axially in the same plane P1 and the rear spring links are disposed axially in the same plane P2.
