Abstract
The second device comprises: a first surface; a second surface in contact with the first device; and a first hole extending between the first and second surfaces and communicating with the groove of the first device. The third device comprises: a third surface in contact with the first surface; a second hole opening on the third surface and communicating with the first hole; and a flow path communicating with the second hole and opening on the third surface. When viewed along a first direction from the first surface toward the second surface: the diameter of the second hole is greater than the width of the flow path; the diameter of the first hole is greater than the diameter of the second hole; the center of the second hole is located within a position surrounded by the first hole; and the flow path does not intersect the first hole at two or more locations.
