A resonance type compressor is provided to install a spring having the same resonance frequency as or similar to reciprocation frequency of a piston to reciprocate the piston with little power, thereby reducing electricity consumption. A compressor(100) includes a connecting rod(174) connected to a rotary shaft(110), a piston(172) having one end connected to the other end of the connecting rod, a cylinder(171) containing the other end of the piston for guiding reciprocation of the piston, and a housing(190) where the cylinder is fixed. Resonant springs are installed in the compressor, having one end connected to the piston and the other end connected to the housing. At least one spring support bar(180) has one end fixed at the piston to protrude a free end in a radial direction of the piston. The resonant spring has one end connected with the free end of the spring support bar and the other end connected to the housing to expand and contract in parallel to a moving direction of the piston.
