At least one of the wall surfaces of the common chamber, along the predetermined direction, has a pressure absorbing surface with a rigidity lower than those of other wall surfaces and configured to absorb a pressure change, and the pressure absorbing surface is formed by a pressure absorbing member having a non-uniform thickness.
