To provide an artificial medical treatment spring manufacturing apparatus for manufacturing artificial medical treatment spring including a micro nano-bubble and achieving enhancement of the treatment effect and cost control.

The artificial medical treatment spring manufacturing apparatus 1 has a radon carbon dioxide micro nano-bubble generating part 2 with a bubble generating part container 4. Carbon dioxide is fed to an underwater pump-type micro nano-bubble generating machine 31 from a solid bath agent 18 which generates carbon dioxide, and the underwater pump-type micro nano-bubble generating machine 31 blends carbon dioxide micro nano-bubbles in hot water introduced into the bubble generating part container 4. Hot water including carbon dioxide micro nano-bubbles further includes radon by virtue of a radium ore layer 32, and as a result, hot water including radon carbon dioxide micro nano-bubble including is generated as the artificial medical treatment spring.
