    摘要： Provided are an orifice member, and a differential-pressure flow meter and a flow-regulating device using the orifice member, that allow purging to be carried out easily when changing the fluid to be circulated, that are less likely to cause contamination and leaching of impurities to the circulated fluid, and that can be easily produced. The flow-regulating device includes a first pressure-measuring device (object to be connected to) that is connected to one end of the orifice member, and a second pressure-measuring device (object to be connected to) that is connected to the other end of the orifice member, and a flow-regulating valve that is connected to the downstream side of the differential-pressure flow meter, which includes the above-mentioned units. In the orifice member, a tube portion, one end of which is connected to the first pressure-measuring device and other end of which is connected to the second pressure-measuring device and whose internal part forms a channel connecting the first and second pressure-measuring devices, and an orifice provided inside the tube portion are integrated.

    摘要： Provided is a fluid device unit structure in which a chemical solution stagnation portion that is formed between a valve of a main fluid flow path and a branching point of a return flow path is minimized to cause hardly any solidification of a chemical solution. In the fluid device unit structure in which a plurality of fluid devices that are connected via flow paths are integrated on a base member (10) to form a single unit, and the main fluid flow path (11) and the return flow path (12) formed in the base member (10) are respectively provided with a first valve (20) and a second valve (40) for switching the flow paths, the branching inlet (12a) at which the return flow path (12) branches from the main fluid flow path (11) is close to the upstream side of the first valve (20).
