PROBLEM TO BE SOLVED: To provide a fluid control valve which includes a pressure loss reducing structure and is compact. SOLUTION: The fluid control valve 1 with a valve main body 11 is provided which has a valve hole 22 which communicates with an input port 21 and is formed vertically to a flow channel direction of the input port 21 and an output port connecting portion 23. In the fluid control valve 1, when it is defined that a cross-sectional area of the valve hole 22 at an end face at a side of the output port connecting portion 23 of the valve 22 is S1 and a cross-sectional area of the output port connecting portion 23 is S2, S1:(S2-S1)=1:(a numerical value more than 4) is established. Hence, a contribution is made to an energy-saving measure due to ensuring a necessary quantity because of eliminating chips even when the chips have reached an exhaust nozzle of a working machine and besides a contribution is also made to reduce an occupied space by a manufacturing line due to downsizing the fluid control valve 1.
