The present invention provides a floatation tank which is provided to have self-buoyancy to continuously and stably make a supported body float on the water, wherein the floatation tank does not lose buoyancy even when a part of the floatation tank is damaged and water leaks in the damaged part. The floatation tank comprises multiple assembled bodies having a container shape by having spaces formed therein, wherein the bodies are assembled by having connection parts which are mutually connected to partition the spaces. |
