To provide a fluid control device further enhancing safety.
In the fluid control device, a normally closed fluid control means 16 controlling the start and stop of the flow of fluid, a tool use detecting means 18 and a tool 17 are connected in a flow passage 15 where the fluid flows from the upstream side in succession, the tool use detecting means detecting the state of the fluid when use of the tool is started while the fluid control means stops the flow of the fluid, a learning storing part 33 for learning beforehand a change of the state of the fluid when use of the tool is started while the fluid control means stops the flow of the fluid, a pattern detecting part 34 detecting a state pattern of the fluid when use of the tool is actually started while the fluid control means stops the flow of the fluid, and a learning determining part 35 comparing a signal stored in the learning storing part and a signal detected by the pattern detecting part and allowing the flow of the fluid by the flow control means when these signals agree with each other are provided.
