To provide a pipe for geothermal heat exchange which has no possibility of breakage during use by a flaw that can be generated at the time of embedding work under the ground, being capable of suppressing degradation under ultraviolet rays in the case where it remains exposed outdoor until completion of another construction work that is performed at the time of embedding.

In a geothermal heat pump system, a geothermal heat exchange pipe 10 embedded underground includes a resin main tube 11 and a resin cover layer 21 that covers the outer peripheral surface of the resin main tube 11, the cover layer 2 contains a weather resistance agent for preventing degradation under ultraviolet rays, and the resin cover layer 21 keeps unbonded to the resin main tube 11 to allow peeling of the resin cover layer 21 from an end part connected to a heat pump and an U-shaped joint.
