Abstract: In An energy treatment system, a judgment section judges whether a vicinity of a treated target, with which an end effector is in contact, is filled with a liquid, in a state that the end effector is in contact with the treated target and a driving current is being output from an output section. In the energy treatment system, a controller executes at least one of stopping an output of the driving current from the output section and issuing an alert to an effect that the liquid is not filled, based on a fact that the judgment section judged that the vicinity of the treated target is not filled with the liquid.
