Disclosed is a heat pump which follows an intermediate form between an ideal Carnot cycle and a Stirling cycle and which, as the same time, has high thermal efficiency as heat is transferred from low temperature to high temperature due to a heat cycle caused by the compression and expansion of a gas by means of an external motive force. The heat pump can comprises: a cylinder which accommodates a working gas on the inside; a heat discharge part which is located at the front end part of the cylinder, and which discharges, to the outside, heat created in the working gas during the compression of the working gas; a heat absorption part which is located at the lower end part of the cylinder, and which is formed in such a way that the working gas absorbs heat from the outside when the working gas expands; a piston which is housed inside the cylinder in such a way as to describe a linear reciprocating motion, and which is formed with an opening in such a way that the working gas makes direct contact with either the heat discharge part or the heat absorption part, and which includes the compression and the expansion of the working gas; and drives part which supplies a motive force to the piston in such a way that the piston moves with a linear reciprocating motion relative to the cylinder.
