A compressor includes a case, a compression unit having a cylinder, a piston disposed inside the cylinder, and a driving unit for reciprocating the piston, and a support unit elastically supporting the compression unit to be spaced apart from an inner surface of the case. The support unit includes a wire spring having a plurality of linear portions arranged in parallel with one another and curved portions each connecting two adjacent linear portions. The wire spring includes a first wire spring and a second wire spring symmetrically disposed with each other. The wire spring includes a connecting portion connecting the first wire spring and the second wire spring, and the connecting portion is supported by the case. Accordingly, a simplified structure can be obtained and a manufacturing cost can be reduced.
