A head is formed by stacking a plurality of plates including a cavity plate and a manifold plate, and includes a plurality of manifolds formed in the manifold plate, a communicating channel which makes the manifolds formed in the manifold plate communicate, and a plurality of pressure chambers formed in the cavity plate, which communicate with the manifold. Each pressure chamber is isolated by a partition wall of the cavity plate. Since the communicating channel and the pressure chambers are formed at different positions in terms of height, it is possible to widen a width of the communicating channel without widening an interval between the pressure chambers, and it is possible to accelerate a movement of a liquid between the manifolds.
