At least a part of the first reservoir overlaps the second reservoir when seen in plan view. A first compliance substrate is provided in the first reservoir on the second reservoir side on the side opposite to the inlet. A second compliance substrate is provided in the second reservoir on the side opposite to the first reservoir.
