An ink jet head includes a first liquid path, the end of which defines a discharge port through which ink is ejected, and a second liquid path having a discharge energy generating element for generating energy to be used for discharging the ink through the discharge port, the discharge energy generating element including a heat generating element for applying heat to discharge ink, the discharge energy generating element generating pressure when driven. The first liquid path is in fluid communication with the second fluid path in the vicinity of the discharge energy generating element, and the first and second liquid paths are substantially parallel to one another. A wall is disposed at least partially above the discharge energy generating element, this wall having a slanted surface which guides the pressure above the discharge energy generating element generated when the discharge energy generating element is driven into the first liquid path and toward the discharge port. At least a portion of the first liquid path is located above the discharge energy generating element and is remote from the second liquid path.
