A supply port (2200) is located in the container supplying ink to the recording head. An opening (5) in the container allows the inside of the container to communicate with the atmosphere. The cavities provided by non-contact between the porous material and the container inside walls exist where the communicating port is formed, opposite from the opening. The head includes a thermal energy generating unit causing film boiling.
