Abstract
To provide a fluid control valve that enables the internal volume to be reduced and, for example, the falling response performance to be improved without compromising the accuracy in controlling a pressure, a flow rate, and so on of fluid, a fluid control valve includes a valve seat portion, a valve body capable of making or breaking contact with the valve seat portion, a fluid resistance, and a pair of clamping members that clamps the fluid resistance. The fluid resistance and the pair of clamping members form an in-valve space in which the valve body or at least part of an actuation member that moves the valve body is housed. Fluid passes through the fluid resistance from the downstream-side in-valve space and flows out to the outside.
