Pressure control device
A pressure control device reliably preventing foreign matter from flowing beyond a filter unit to the downstream side. The pressure control device includes a body and a cylindrical filter unit. The body has a flow path including a groove and a widened part. A depth of the groove from an upper surface to a bottom is a first depth. The widened part is connected to the groove, extends from the upper surface to the bottom, 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 passing through the flow path. A depth of the widened part from the upper surface to a bottom surface is a second depth larger than the first depth. The widened part includes a receiving part that a part of the filter unit enters.
