To raise hot water from a hot spring deep well at a high flow rate, while minimizing falling of temperature and to reduce the installation cost.

This pump device 2 is mounted inside a case body 1, and a pipe 4 for raising hot water, which is inserted and arranged inside the hot water deep well 3 sunk in an underground in a communicating state with an inside of the case body 1 is continuously arranged to the case body 1. The diameter of the pipe 4 for raising hot water is smaller than that of the hot water deep well 3. A lead-out pipe 5 which leads to a proper position the hot water raised from the pipe 4 for raising hot water by a pump operation of the pump device 2 is continuously arranged to the case body 1 in a communicating state with the inside of the case body 1, and the pipe 4 for raising hot water is mounted to a target depth, which is near a hot spring vein inside the hot spring deep well 3. At this time, the hot water pumping device for deep well hot spring is constituted to be long in the length of the pipe 4 for raising hot water, such that the pump device 2 inside the case body 1 is not mounted near a deep hot spring vein inside the hot spring deep well 3 but is mounted to a position which is immersed at least under a water level in the hot spring deep well 3.
