A fluid control valve includes a passage block formed with a passage, a valve seat provided in the passage block, and a valve element to be brought into contact with or separated from the valve seat. The fluid control valve is configured to open and close the passage by movement of the valve element with respect to the valve seat to control a fluid. The fluid control valve further includes a shape-changeable part which changes its shape in association with the movement of the valve element. The shape-changeable part has a surface formed with a monomolecular film of fluorosilane material.
