PROBLEM TO BE SOLVED: To open a control valve just in start of use of a tool on the downstream side, and to enhance convenience and safety by closing the control valve when not used. SOLUTION: This fluid controller is provided with a tool use detecting means 18 for detecting a use state of a fluid in the tool 17 on the downstream side, based on the fluid, and an opening and closing operation control means 19 for opening a fluid control means 16 when detecting the start of the use of the fluid, based on a signal from the tool use detecting means 18, and for closing the fluid control means 16 when detecting the stop of the use of the fluid, wherein safety is enhanced by closing the control valve (fluid control means 16) all the time when not using the fluid, and simplification and workability are enhanced by detecting the using state of the fluid based on the fluid.
