There is provided a rotary heat pump capable of realizing further miniaturization, compared with a current status. As means of solution, a rotary heat pump includes: a rotary drive section including: a rotary shaft; a stationary gear; a rotor that has a rotor gear engaged with the stationary gear and that makes an eccentric rotation; a rotary housing along a peritrochoid curve defined by the eccentric rotation of the rotor; and a first side housing and a second side housing that cover one end side and the other end side of the rotary housing and that fix the stationary gear; a heat exchange fin provided in each of a compression region that is demarcated by the rotor and the rotary housing and that has a smallest planar area and an expansion region that has the largest planar area; and a heat insulation portion formed in a boundary portion between the compression region and the expansion region.
