As viewed in a first direction from the first to second surfaces, the second hole has a diameter greater than a width of the flow path. The first hole has a greater diameter than the second hole. The second hole has a center surrounded by the first hole. The flow path intersects with the first hole at not more than one point or does not intersect with it.
