  In the present embodiment, the fluid control unit 10 can eliminate the need for tubes and pipes that function as joint members and flow path members, and the flow path portion 21 can be configured with a small number of components, and the desired cleanliness can be easily maintained.

  In this embodiment, since the plate member 30 is a thick plate member, the depth of the groove portion 31 can be adjusted in advance, and the flow channel area in the flow channel portion 21 can be varied in advance. Since the cover plate member 40 is a thin plate member, the attachment hole portion 70 can be easily manufactured, and the fluid device 50 can be easily brought into contact with the flow path portion 21.

In this embodiment, the fluid flows from the upstream joint member 25 toward the downstream joint member 27 and is distributed from the upstream side to the downstream side. However, the present invention is not limited to this. The upstream side and the downstream side may be opposite to each other.
