1. A fluid control device that is disposed in a flow path of a fluid and that enables data regarding an internal operation to be acquired, the fluid control device comprising:
a cylindrical sensor hood to which one or more sensors for detecting an operation in the fluid control device are attached;
a valve body connected to the sensor hood;
a diaphragm held below the sensor hood, inside the valve body;
a box-shaped cover portion that covers the outer periphery of the sensor hood; and
a circuit board that is electrically connected to the sensor(s),
wherein the longitudinal direction of the valve body runs along the flow path direction in a state where the valve body is disposed in the flow path,
wherein fitting portions are formed as a pair in positions facing each other on an inside of side walls of the cover portion that run along the longitudinal direction of the valve body,
wherein the sensor hood abuts on the pair of fitting portions,
wherein the circuit board is configured such that a thickness direction of the circuit board and the longitudinal direction of the valve body are arranged in the same direction on a inside of the cover portion,
wherein the circuit board is housed along the side walls of the cover portion, and
wherein the cover portion and the circuit board are arranged on an inside of the valve body in a width direction.
