Abstract
The disclosure provides a pressure control device that improves the workability in assembling a body and a filter unit. The pressure control device includes a body and a filter unit. The body has a flow path that includes a groove and a widened part. The widened part is connected to the groove, extends to a bottom of the groove, and has a width larger than a width of the groove. The filter unit is housed along a depth direction of the widened part to capture foreign matter mixed in a fluid that passes through the flow path. The filter unit includes a cylindrical frame and a flat plate-shaped filter member, wherein the frame includes a through hole part that penetrates in a direction orthogonal to a central axis, and the filter member is disposed to block the through hole part.
