Abstract: A pressure control device includes: a body having a groove-like channel containing a groove part and a widened part; and a filter unit having a cylindrical frame including a through hole part penetrating in a direction orthogonal to a central axis and a plate-shaped filter member disposed to cover the through hole part and supported on an inner side of the frame. The filter unit is accommodated in the widened part with a direction of the central axis of the frame being arranged along a depth direction of the widened part. The frame includes a convex part orthogonal to the penetrating direction of the through hole part and protruding toward an outer side of the frame.

Abstract: A pressure control device includes: a body having groove-like channel containing a groove part and a widened part; a filter unit having a cylindrical frame formed of an elastic material and including a through hole part penetrating in a direction orthogonal to a central axis and a plate-shaped filter member disposed to cover the through hole part and supported on an inner side of the frame. The filter unit is accommodated in the widened part with a direction of the central axis of the frame being arranged along a depth direction of the widened part; and a separate plate installed to the body to cover the groove-like channel in a state in which the filter unit is accommodated in the widened part. The frame has a length along the central axis greater than a depth of the widened part.
